OptoNet Member › GRINTECH GmbH
GRINTECH is one of the leading manufacturers of gradient index (GRIN) microoptic 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. The individual lenses have a diffraction-limited numerical aperture of up to 0.45. The flat optical surfaces enable easy assembly to micro-optical lens systems and complex components according to flexible customer-specific requirements.
GRINTECH was founded in December 1999 as a spin-off from the Fraunhofer Institute for Applied Optics and Precision Engineering Jena.
