GRINTECH – Gradient Index Optics Technology

Logo GRINTECH GRINTECH GmbH was founded in 1999 as a spin-off of the Fraunhofer Institute for Applied Optics and Precision Engineering in Jena, Germany. Today, GRINTECH is one of the leading manufacturers of gradient index (GRIN) micro-optic lenses and lens systems based on more than 20-years of experience. GRINTECH delivers medical imaging and biophotonic technology, optical metrology and sensor technology to growing markets. GRIN-lenses are miniaturized lenses having extraordinary good optical performance and flat optical surfaces.
The optical power of GRIN-lenses is achieved by a refractive index (GRadient INdex) profile fabricated by a non-toxic silver and lithium ion exchange process in glass. Our unique rod and cylindrical micro lenses have typical dimensions from 200 µm to 2 mm. With diffraction-limited numerical apertures up to 0.45. The flat optical surfaces enable an easy assembly to micro-optical lens systems tailored to your specific requirements.


Logo Micro-EpsilonMicro-Epsilon is a medium-sized family-run company, which plays a leading role in measurement technology. For more than 45 years we have continuously offered reliable, high performance, unique solutions particularly when high precision measurement or inspection is required. Our product range covers sensors for the measurement of distance and displacement, sensors for IR temperature measurement and color detection, as well as systems for dimensional measurement and defect detection.
Innovative products that provide the very highest levels of precision are created through intensive, research and development processes, unique know-how and a broad network of collaborative operations, which are essential for such high performance measurement systems.We understand that our customers are our business partners, which creates a win-win situation for both parties. Our products often provide customers with a genuine competitive advantage. However, this is only the case if the products are higher precision and so provide a clear, decisive competitive edge. With more precision.

Concept Laser GmbH

Concept Laser GmbH, which was founded in 2000 by Frank Herzog, is one of the world’s leading providers of machine and plant technology for the 3D printing of metal components. The patented LaserCUSING® process – powder-bed-based-laser melting of metals – opens up new freedoms when it comes to configuring components and also permits the tool-free, economic fabrication of highly complex parts in fairly small batch sizes. The company’s customers come from many different sectors of industry, for example medical and dental technology, the aerospace industry, toolmaking and mold construction, the automotive industry and the watch and jewelry industry. Concept Laser’s 3D metal printers process, among other materials, powder materials of stainless steel and hot-work steels, aluminum and titanium alloys and – for jewlery making – precious metals.

InVerTec – Institut für Innovative Verfahrenstechnik e.V.

Logo InVerTecInVerTec was founded in 1997 as a non-profit organization with the aim of practicing interdisciplinary fundamental research and applied science in the field of combined electrothermal treatment and process intensification. Interdisciplinary R&D projects from a concept to a bench-scale model to the pilot plant scale are carried out in cooperation with our partners in the industry, at institutions and by teams workgroups at the University of Bayreuth. in particular at the chairs in the Faculty for Engineering Sciences.
InVerTec provides pilot plants for conceptual and laboratory-scale research, performs experimental work, and does plant engineering. Additionally InVerTec installs and lunches pilot plants at our industrial and institutional partners.
