The latest addition to our CompactLine: the AvaSpec-Mini-NIR!
The AvaSpec-Mini-NIR is a compact near-infrared spectrometer, based on a combination of our popular AvaSpec-NIR256-1.7-EVO and Mini-series.
Like our other CompactLine spectrometers, this device is only the size of a deck of cards and USB powered, which makes it easy to integrate into other devices, including but not limited to OEM handheld applications. Since the AvaSpec-Mini-NIR has no moving parts it is very robust and can be used virtually any environment!
Of course, the AvaSpec-Mini-NIR works seamlessly with our AvaSoft software and the Windows and Linux libraries we have available.
If size is not the most important factor for your application, we recommend the AvaSpec-Mini-NIR's bigger brother, the AvaSpec-NIR256-1.7-EVO that is bigger in size but offers slightly higher sensitivity levels.
This versatile miniature NIR spectrometer is well suited for various applications, including food analysis and the recycling industry. Below are some application examples for this instrument:
The AvaSpec StarLine family of instruments is comprised of high-performance spectrometers which exceed the demands of most general spectroscopy applications. This instrument line offers a wide array of solutions for various uses, while providing excellent price-to-performance ratios.
Our AvaSpec-ULS2048CL-EVO and AvaSpec-ULS4096CL-EVO are based on CMOS arrays and are able to measure wavelengths from 200 to 1100 nm. The AvaSpec-FAST series of instruments is especially designed for high-speed acquisitions, such as pulsed light source and laser measurements.
Instruments in the AvaSpec StarLine family are designed to perform in a variety of applications such as:
The AvaSpec StarLine instruments are fully integrated with Avantes' modular platform, allowing them to function as both stand-alone and multi-channel instruments.

The entire AvaSpec StarLine is available as an individual lab instrument, as well as an OEM module for integration into customers' existing systems.
The new Avalight-HPLED, a compact, low-cost light source meant for fluorescence applications. This high-power version was made for more demanding applications compared to our regular LED light source.
Our AvaLight-HPLED light sources produce continuous or pulsed spectral output at different wavelengths. All sources have an SMA-905 connector to connect fiber optics and come with a 5V/1.6A power supply. This high-power LED light source can be used as a DC source or pulsed with a programmable Pulse Width Modulation (PWM), supplied by an AvaSpec-USB2 or EVO spectrometer (IC-DB26-2 cable needed).
Get the best out of two worlds with the AvaLight-DHc. It has both a deuterium light source and a halogen light source, providing you with adequate light between 200 and 2500 nm for nearly all absorbance chemistry applications. Deuterium emits light between 200 and 550 nm, where the halogen takes over up to 2500 nm. Coupling to the rest of your spectroscopy system is easy with the SMA connector.
This light source is recommended in settings with large fiber cables or direct-attachment to a cuvette holder such as the CUV-DA, due to its relatively low output energy. The integrated TTL-shutter makes saving a dark measurement very simple in combination with AvaSoft (extra IC-DB26-2 needed).
Optionally the AvaLight-DHc is available in a rack-mountable version, to be used in the 19” rack or the 9.5” desktop system.
In need of more power than the AvaLight-DHc? The AvaLight-DH-S is Avantes’ most powerful deuterium halogen source. Like the DHc, the DH-S is also a combined deuterium and halogen light source, capable of transmitting light in the UV/VIS/NIR-range, but has 35 times more halogen output and up to 300 times more deuterium power. The source has a prominent 656 nm deuterium peak which can limit dynamic range (see Avalight-DH-S-BAL as an alternative). It includes a focusing lens assembly, to fully utilize the possibilities and size of your fiber.
The AvaLight-D-S is a deuterium light source only, making it a great option for measurements in the UV range, 190 to 400 nm. The AvaLight-D-S-DUV version starts even lower at 175 nm, for your deep-UV experiments. This version also offers twice the intensity at 200 nm.
The output of the AvaLight-DH-S is optimized for fibers or bundles up to 600 micrometers. For larger fibers the focal point is manually adjustable to optimize the light coupling into your fiber.
The AvaLight-DH-S is a powerful deuterium halogen source, but, like any unbalanced deuterium halogen source, it does have a very dominant alpha peak at 656 nm. This is why Avantes developed the DH-S-BAL, in which this peak is drastically reduced by a dichroic filter. This means less power, but an increase in the dynamic range of a factor 20. A comparison spectrum as taken with a standard AvaSpec-2048 is shown on the next page.
The light source delivers a continuous spectrum with high efficiency. The highest stability is in the ultraviolet, visible and near-infrared range, from 200 to 2500 nm. An integrated TTL-shutter and filter holder for filters of up to 50 x 50 x 5.0 mm are included. The TTL-shutter can be controlled from any AvaSpec spectrometer, which means the auto-save-dark option in AvaSoft software can be used (please note: IC-DB26-2 cable is needed).
The AvaLight-XE-HP is a pulsed xenon light source, perfect for ultraviolet applications, such as fluorescence. This high-power light source comes in a compact housing, which makes it very well-suited for integration into a customer’s existing systems. Compared to the AvaLight-XE (2W), the XE-HP provides significantly more power.
When connected to your AvaSpec spectrometer through the Y cable, the flashes are synchronized with the data collected by the spectrometer. The number of flashes per scan can be selected in AvaSoft.
The AvaLight-XE is a pulsed xenon light source, perfect for ultraviolet applications like fluorescence. When connected to your AvaSpec spectrometer through the IC-DB26-2 cable (sold separately), the flashes are synchronized with the data collected by the spectrometer. The number of flashes per scan can be selected in AvaSoft.
With a special DUV bulb, the AvaLight-XE can be used for deep-ultraviolet applications (below 200 nm). A special direct-attach cuvette holder is available for your fluorescence applications. For transmission measurements, the Avalight-XE can be used in conjunction with the CUV-ATT-DA which has an iris attenuator to limit the light output and to avoid saturation.
Calibrating your spectrometer has never been easier: the AvaLight-HAL-CAL-Mini and Avalight-DH-CAL are NIST(National Institute of Standards and Technology) traceable, calibrated light sources to measure absolute spectral intensity with.
The AvaLight-HAL-CAL-Mini is a compact, affordable light source. It is calibrated for the visible range (350-1095 nm). Optionally, an extended calibration for the near-infrared spectral range (1100 – 2500 nm) can be ordered. It has a built-in diffuser, a cosine corrector with SMA adapter and comes with a calibration file in ASCII format. Calibration can be done using the AvaSoft software.
The AvaLight-HAL-CAL-ISPxx-Mini is a special version of the Avalight-HAL-CAL-Mini, which enables coupling any of Avantes’ AvaSphere-xx-IRRAD integrating spheres to the lightsource (xx = 30, 50 or 80) for calibration. This source is supplied with a special bottom plate to stabilize the AvaSphere. The Avalight-HAL-CAL-Mini and Avalight-HAL-CAL-ISPxx-Mini include a power supply.
The AvaLight-CAL-xxx is a spectral calibration lamp, available in Mercury-Argon (253.6-922.5 nm), Neon (337-1084.5 nm), Argon (696.5-1704 nm) Zinc (202.5-636.2 nm) and Cadmium (214.4-643.8 nm) versions. The major lines including their relative intensity and structures are shown below.
The standard SMA-905 connector supplies an easy connection between the lamp and optical fibers, making the AvaLight-CAL-xxx a low-cost wavelength calibration system for any fiber-optic spectrometer. AvaSoft-Full spectroscopy software includes an automatic recalibration procedure.
The AvaLight-CAL-Mini, AvaLight-CAL-AR-Mini, AvaLight-CAL-Neon-Mini all come in the Mini-housing and are equipped with a connector at the rear enabling to switch the unit on/off remotely with a TTL signal.
The need for greater efficiency, quality, and safety in agricultural production is increasingly being addressed through the introduction of spectroscopic techniques during and after production and processing. The rugged and field-deployable characteristics of compact, dispersive array spectrometers along with the inherent benefits of fiber-optic sampling are driving increasing adoption of this technology in agricultural operations.
The application of spectroscopy to botany, horticulture and agriculture enables sophisticated spectral analysis of wavelengths of interest to plant scientists. Fiber-optic spectrometers provide the added benefit of real-time in-situ measurements of plants. Avantes’ instruments are being used in a variety of plant applications ranging from chlorophyll detection in crops to the measurements of sugar (ºBx or brix) in fruit, and radiometric measurements of light levels in greenhouse environments.
Medical and biomedical researchers, as well as OEMs frequently utilize spectroscopy techniques for clinical and research processes. Ultraviolet, visible and near-infrared wavelength ranges are measured for a variety of medical and biomedical applications.
Fiber-optic based spectrometers offer a great value to the industry due to their ability to facilitate in-situ (in vivo) measurements within clinical settings. The fiber-optic interface is often exploited for low cost, disposable testing procedures. Low cost instruments also present the opportunity to bring the lab to the patient. Biomedical analysis can benefit from the superior price to performance ratio realized with using fiber optic spectrometers in place of traditional, higher priced instruments and detectors.
Our instruments are utilized in various medical and biomedical applications such as blood analysis (co-oximetry), endoscopy, tissue fluorescence, capillary electrophoresis, phototherapy and many others. Avantes’ experiences in these industries range from OEM component supplier to research system configurator.
In the field of chemical spectroscopy, there are an unlimited number of applications. Chemical reactions are dynamic processes that vary with changing conditions which result in a various way of techniques.
From enzyme reactions within our cells to photosynthesis in leaves, chemical reactions play a vital role in every aspect of our lives. Factors like concentration, temperature, pressure and the presence of a catalyst affect the speed of a reaction. The study of chemical kinetics is used to characterize these processes and improve our understanding of how these factors and others change the outcome of a chemical reaction.
Ecosystems around the world are facing growing threats. The increasing pace of industrialization, pressure from growing populations and increasing urbanization, as well as climate changes can wreak havoc on emerging economies and have health and social implications. Not surprisingly, researchers, scientists and governments are investing significant resources to monitoring and preventing these environmental hazards.
Spectroscopy is a technique that is very well suited for various environmental applications. Recently, there has been an increase in the need to identify and trace chemical contaminants, especially organic compounds, as they have negative impact on the environment.
In the lighting industry, the focus is not only on manufacturers of different light bulbs and LEDs, but the companies involved in testing and validating these bulbs and LEDs, and the assembly of these products in for instance street lights and solar simulators as well.
Since these products emit light, the connection with spectroscopy is easily made. In this industry, spectroscopy is mostly utilized for real-time monitoring and quality control before, during and after the manufacturing process.
Avantes offers aside a wide selection of spectrometers and the necessary accessories like integrating spheres and cosine correctors to accomodate measurements for the lighting industry.
These systems often need to be intensity calibrated to give the most accurate results. Avantes offers in-house calibration services as well as field calibration sources.
The semiconductor industry can realize significant benefits from spectroscopic measurements during various stages of their processes. Fiber-optic based spectrometers offer a great value to the industry due to their ability to facilitate in situ measurements within processing environments and facilitate near real-time analysis.
Avantes works with semiconductor applications such as end-point detection for plasma ion etching, ion beam etching, photoresist stripping, and chemical/mechanical polishing. Instrument configurations have also been deployed in environments for thin film metrology (inline and offline) and plasma diagnostics.
Sunlight is defined as the total spectrum of the electromagnetic radiation emitted by the sun. On Earth, sunlight is filtered through the atmosphere, and the solar radiation is visible as daylight when the sun is above the horizon. When the direct radiation is not blocked by clouds, it is experienced as a combination of bright light and heat.
The sun is the primary source of energy on Earth. Radiation from the sun strikes the Earth’s atmosphere and begins to be absorbed by air particles and gases, while the remaining energy reaches the Earth’s surface. Earth absorbs much of this radiation, and reflects and emits radiation as well. Even small changes to the balance of this energy system is believed to be able to cause intense shifts in the Earth’s climate.
The measurement needs of the solar industry are quite diverse, ranging from process control applications in the manufacturing of thin film photo-voltaic panels through direct solar measurements and solar simulator characterization.
Avantes has worked closely with a number of industrial and research customers in the solar industry to design spectroscopy and spectroradiometry systems which meet the demands of this fast growing industry.

Reflection spectroscopy, often called reflectance spectroscopy, is often used to non-invasively and non-destructively characterise objects and materials. Comparing the reflected light to the light used for illumination, can tell you a lot about the characteristics and nature of the object or material being researched, for instance exact colors, compounds and more.
When light hits a surface of a material it will either be reflected, absorbed or transmitted through the material (or a combination of the above). The reflectance of this light will depend on the structure and the material properties of the object.
Depending on the reflectance application, a wide variety of light sources, accessories, fiber-optic probes and spectrometers can be chosen, offering you a tailor-made solution for your specific application.
When the object or material you want to measure is more transparent, for instance a filter, glass or fluid, the amount of reflected light is too low to perform a reflection measurement. For (mostly) transparent materials, transmission spectroscopy is the best choice, since it measures the light that passes through the material in comparison to the emitted light, instead of light that reflects from it.
To perform such a measurement, usually a parallel lightbeam is used while utilizing collimating lenses between the fiber optics of the setup. The object of interest is then placed between these collimating lenses to measure what light is transmitted through the material.
The absorbance (also called optical density) of a material is a logarithmic ratio of the radiation falling upon a material, to the radiation transmitted through a material. UV/VIS absorbance measurements encompass a wide variety of chemical and biochemical applications which involve many areas of research and industrial end uses. UV/VIS absorbance can be applied qualitatively and quantitatively in spectroscopic measurement applications ranging from blood parameters to chemical concentrations in process and reaction monitoring.
Fiber-optic spectrometers offer a tremendous value proposition for UV/VIS measurements because of their relatively low cost, small size and ability to be introduced in harsh environments through the fiber interface. Combined with a fiber-optic transmission dip probe, inline flow cells or the more traditional cuvette cell, a fiber-optic spectrometer can accurately and repeatably measure over the range from 200-1100 nm.
Radiometry deals with the measurement of all optical radiation inclusive of the visible portion of this radiant energy. Irradiance is a parameter of radiometry. It describes the amount of radiant power impinging upon a surface per unit area. These measurements can be done in the UV, VIS and NIR wavelength ranges.
Avantes works with a variety of irradiance applications ranging from pulsed solar simulator characterization to free space measurements of radiant sources such as street lights.
Fluorescence spectroscopy, also known as fluorometry or spectrofluorometry, is a type of electromagnetic spectroscopy, which analyzes fluorescence from a sample. It involves using a beam of light that excites the electrons in molecules of certain compounds and causes them to emit light; typically, but not necessarily, visible light. It is a useful technique in many biological (chlorophyll and carotenoid), biochemical (diagnosis of malignancies) and environmental applications.
For most fluorescence applications the amount of fluorescent energy emitted is only 3% of the amount of excitation light energy. Fluorescent light has a lower energy (higher wavelength) than the excitation energy and is usually scattered light. This means it emits energy in all directions.
Raman spectroscopy is a technique that characterizes inelastic scattering of photons in covalently bound molecules. This scattering is then used to define the material’s so-called molecular fingerprint, crystallinity and other specifications. Raman provides an invaluable analytical tool for molecular fingerprinting used in material identification, as well as monitoring changes in molecular bond structure (e.g. state changes, stresses and strains).
Avantes uses the high-sensitivity AvaSpec spectrometers in combination with a wide variety of lasers (including 532 and 785 nm) to give you the best result for your Raman measurements. The spectrometers are appropriately configured according to the wavelength of the laser.
Differential optical absorption spectroscopy, or DOAS, is a technique that is used to monitor pollutants in the atmospheric air. This form of spectroscopy is often used in continuous emission monitoring systems (CEMS).
Avantes instruments are integrated into a variety of CEMS around the world. Due to the high stability requirements of this technique, any of the Avantes thermo-electrically cooled spectrometers are used in this application.
Though it has been around for a few decades, nowadays DOAS is performed by recording two absorption spectra, one as a reference scan through a column of atmosphere (ideally) free of contaminants and one through an identical pathlength containing the contaminant that needs to be analyzed. The light traveling through the measured atmosphere is partially absorbed by trace contaminants along the way following Lambert Beer’s Law of Absorption.
Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy that employs a laser to ablate or vaporize a microscopic layer of a sample’s surface. The resultant plasma caused by this laser ablation process emits light as it cools. This light is then collected and analyzed with a spectrometer for quantitative and qualitative material analysis.
This rapid chemical analysis technique offers many advantages compared to other elemental analysis techniques:
