Gentec-EO’s calorimeters are the only reliable solutions available on the market for high energy measurement. We work with a wide range of materials from surface coatings to the most robust volume absorbers to provide the best solution for your specific application.
For large beams, high energies and special applications that do not fit with the QE or UP series, Gentec-EO can build custom calorimeters to fit special requirements. A calorimeter can be considered as the ideal option when facing one or more of these conditions:
The BD Series are rugged and easy-to-use, simply plug the water-cooling and you’re ready to go! Like our high power HP Series, these beam dumps have a highly resistant absorber that can withstand several kW in continuous mode. Their very large aperture of 100 mm in diameter accommodates even the largest beams.
An isolation tube (available in option) helps reduce the back reflections.
2 models are offered: 4 kW and 12 kW.
Our discrete pyroelectric detectors are a class of room temperature thermal detectors that produce a current output that is directly proportional to the rate of change of temperature when exposed to a source of radiation.
These detectors are ideal for pulsed laser applications. They can be used in applications where small, compact, inexpensive, easily integrated and very sensitive measurement devices are required.
Our Discrete Pyroelectric Detectors range from 1 to 9 mm in diameter and are provided in various configurations: passive or hybrid, high sensitivity or high average power. They present a pyroelectric detector element covered with our metallic coating (MT) and are packaged in a miniature TO-5 or TO-8 can.
The advantages of a pyroelectric detector over other IR detectors are:
Some of our customization options are:
Our large area Pyroelectric Quadrant Detectors provide unique advantages over other laser position and pointing stability detectors like Silicon quads or lateral effect photodiodes.
They are fast, handle high peak power of pulsed lasers without saturation and respond to lasers across the spectrum, from UV to Far IR and even THz.
The QUAD-E is intended for use with pulsed sources at up to 1000 Hz, while the QUAD-P is designed for CW and High Repetition Rate (Quasi CW) sources.
Both types of detectors can also be used as standalone units, in an analog mode, for incorporation into your own system application. We can provide a Lemo pigtail cable for this purpose.
The thermal disks in the UD Series were designed for integration into laser systems. They are the solution if you are engineering the cooling and signal processing into your system already.
We offer many sizes and absorber choices.
If you select a thermal disk, you can also use our external PCB for signal anticipation, amplification and filtering.
We can also integrate a PCB inside complete detectors.
Modifying existing products and developing fully customized solutions to meet the special needs of our customers is an important part of what we do at Gentec-EO.

Through cooperation with several leading research facilities around the world, Gentec-EO has become an expert in manufacturing, calibrating and servicing calorimeters for use in high energy inertial confinement fusion calorimetric measurement.
Using NIST traceable sources and proven calibration techniques, Gentec-EO’s large calorimeters, with a calibration uncertainty of ± 3% and a repeatability better than ± 2%, are the most accurate large aperture measurement devices on the market.
We have designed calorimeters for 16 kJ beams. We have built them as large as 420 x 427 mm in aperture size, to withstand pulse energy densities of more than 15 J/cm2.
We are happy to push these limits even further!
Thanks to our unique design, our HP series, high power detectors for measuring multi-kW lasers, are lighter and more compact than any other high power detector on the market.
We offer regular detectors, available off the shelf, with models up to 12 kW and custom-made detectors, available on demand and designed for your needs for up to 120 kW!
Square, round or even rectangular apertures are possible, up to 500 mm x 500 mm in size.
Capture EVERY pulse, with no sampling, at high repetition rates up to 200 kHz.
The MACH 6 is the only energy meter in the world that can measure this fast!
Our six choices of detector heads in the M6 series cover energies from a few picojoules to 0.2 J and a broad range of wavelengths.
Our proprietary W absorber for power detectors allows us to build laser power meters with the highest damage threshold for maximum average power density.
With up to 100 kW/cm2, you will be able to measure laser beams at their focal point, even at power levels of tens of watts.
At Gentec-EO, we understand that the essence of our business since over 45 years has been delivering accuracy. There are no half measures: it either measures accurately or we don't make it.
This is why one of our company’s values is rigor, because our customers expect nothing less.
