B&M Optik GmbH is a mid-sized business headquartered in Limburg an der Lahn (Hessen). Since being incorporated, we have developed an outstanding reputation as a reliable and trusted manufacturer and partner for optical assembly elements and components. As an owner-operated business with tradition and experience, we know how important it is to respond to customer requirements individually. This is why we place a top priority on cultivating the collaboration with our customers.
We also provide the best-possible quality in everything we do - from the product to customized consulting and ending with short response times for solutions to problems. Our day-to-day objective is to repeatedly exceed these expectations, entirely to the benefit of our customers. You too should get to know our innovative products, technologies, and expertise. We will gladly support you during the development phase of your product. We believe that the sooner we can work hand-in-hand, the faster we can found a solution that meets your engineering and commercial needs.
Finish moulding hot glass into optical elements is an advantageous technology for technical optics. By continuing to develop precision tools, manufacturing processes, and the technology itself, we have in recent years significantly improved the quality of optical components.
Moulding tools can be manufactured cost-effectively and in 4 – 6 weeks. At B&M Optik we use glass rods or gobs as the raw material, which are partially heated to the correct temperature and then moulded in the moulding tool. The parts are then stress-relieved or tempered depending on the application of the spherical or aspherical glass lenses.
For use in LED optics, we very frequently employ finish moulded aspherical lenses with blank, precision-textured, medium-textured, or coarse-textured plane surfaces. Alternatively, and depending on customer need, moulded plano convex lenses, cylindrical lenses, biconvex lenses, freeform lenses, or a lens array can also be used as LED optics.
The optimal beam angle can be adjusted for the respective LED light application as a function of the LED beam surface and the distance between the plane surface of the optical lens and the LED.
We will gladly advise you on the choice of the LED, the technical optics, and the optical design of your application.
Our manufacturing and final inspection of the optical components is based on DIN ISO 10110 to ensure uniform, controllable quality of the spherical lenses.
Using CNC manufacturing processes, we will manufacture your plano convex lenses, biconvex lenses, plano concave lenses, biconcave lenses, achromatic lenses (doublets), quartz lenses, cylindrical lenses, menisci, and spheres.
We can also offer all our optical components with AR coating and also as a subassembly.
Prisms are plane and precise optical elements that are precision-shaped by grinding and polishing and have optical effects. They are used for optical beam guidance and deflection.
The angles, orientation, and the number of surfaces determine the type and function. Optical prisms need to meet a wide range of requirements. In optical systems, our prisms ensure that light is deflected exactly to your technical specifications.
Let us know what your specifications are so that we can give you a customized quote. The advantage of prisms is that these optical systems can be realized with a minimum of space requirements.
Various optical filters are used to selectively absorb user-defined wave lengths of the light. In addition to custom solutions, our offer includes many specialty products, glass color filters (various shapes and types), thermal absorption filters, plastic color filters, thermal reflection filters (IR-2 / IR-4 / IR-5), interference filters, bandpass filters, shortpass filters, longpass filters, UV filters, and customer-specific filters of all types on request and to your specifications.
Injection molding methods are used to manufacture plastic lenses and optical elements.
These methods are used to cost-effectively manufacture directly usable molded parts in large quantities. The specified plastic type is placed into an injection molding unit of an injection molding machine, and is then injected into an injection molding tool under high temperatures. The tooling used for this purpose are high-precision molds.
The tool cavity determines the shape and surface texture of the finished, injection molded optical element. The surface of the optics provides essentially unlimited design freedom.
Our factory in Pirna has various coating capabilities on four different systems. These are reflective and anti-reflective coatings in the respectively desired wave length range.
Our offer includes anti-reflective coatings, highly-reflective mirror coatings, metallic splitter coatings, dielectric coatings, beam splitter and filter coatings.
Any glass type, and even plastic (depending on application), can be used as substrates. The coating design must of course take into account the material properties.
On request, we also provide subassembly services for opto-mechanical components. From lens assemblies, oculars, magnifiers, mounting holders, mountings, housings, to other subassemblies with the corresponding optical components from B&M Optik, we will supply the assembled, typically cemented and inspected subassemblies according to your requirements and specifications.
We will manufacture the individual parts exactly to your requirements, and will realize the desired optical function by integrating your components to specifications; alternatively, we will use the mechanical components inspected and supplied by you for the sub-assembly.
We will gladly support any of your assembly needs. Do not hesitate to contact us so that we may jointly look toward the optical future.
Aspherical surfaces perform the task of minimising the aperture error invariably found in any lens. In comparison with a spherical lens with a comparable diameter and focal length, aspherical lenses have a lower aperture error. Under certain conditions it is possible to improve image defects such as coma, distortion and astigmatism. Since grinding, as for spherical surfaces, is not possible on conventional machines, the aspherical lenses are moulded. We recommend limiting the use of moulded lenses to condenser optics and simple lighting systems. The lenses must be designed such that demoulding is possible: lenses can be supplied in an angular design with offset rim and in an array form version, for example

This is the case because we are in lock-step with the times, technology, and design.
Our customers know us as a responsive, reliable, and innovative partner. You can confidently place the development and manufacturing of your prototypes, low-volume, and high-volume orders in our expert hands.
B&M Optik products are found in a significant number of technical lighting applications.
Everywhere in our daily lives, we are surrounded by sensors, smoke alarms, automatic doors, the technology in our smartphones and cars, and in countless other places. Sensors are the “eyes” of a factory or a device - and we improve the performance of these systems as optics engineers.
Nowadays, a sophisticated industrial plant is no longer conceivable without sensors. Likewise, a successful sensor technology manufacturer is unimaginable for us without collaborating with B&M Optik.
Sensors and sensor technology are an indispensable key technology for today’s times, and the expectations placed on this technology are extremely high, even in the coming years.
Together with its customers, B&M Optik repeatedly confronts precisely these expectations, while backing the high standards with tireless support, continuous research & development, and tightly-controlled quality management.
Our specialty is to support our customers for lighting applications related to dental and medical device engineering, from research to development, and also for manufacturing your treatment and research devices.
Our lenses for LEDs permit shadow-free illumination of the treatment location.
Optical lenses permit and improve a wide range of medical methods, for example with the help of lasers.
Our components are also used for cosmetic laser treatment. A particular related challenge is that the equipment – such as endoscopes and otoscopes, as well as surgical instruments – must be sterilized.
Automation is the autonomous operation of machinery that reduces or makes human communication or control redundant, provided everything works as intended. Ford Motor Company was the first to use automation in the late forties. Since then, automation technology has become the engine of today’s modern society.
Processes can be seamlessly controlled and observed from afar. The related components are mechanical, electrical, electronic, and optical elements from control technology, drive technology, sensor technology, and from communications technology.
Laser optics are used in a wide range of laser devices and laser applications, such as beam guidance or material processing.
B&M laser optics feature specific substrates, coatings, or a combination of these, giving them high quality at specific laser wave lengths or across entire wave length ranges. A known challenge is that a number of laser optics have high damage thresholds, either for pulsed or CW lasers.
This means that when laser optics are used in combination with an insufficient laser damage threshold, the optical component of the laser can be damaged. And here again, our customers benefit from B&M Optik’s decades of experience. Do not hesitate to contact us, and let us celebrate our common success stories for your next project.
