Company

GRINTECH is one of the leading manufacturers of gradient index (GRIN) micro-optic lenses and lens systems based on more than 10-year experience.

GRINTECH delivers to growing markets like information technology, medical and biomedical technology, optical measurement and sensor technology. 

The optical power of GRIN-lenses is achieved by a refractive index profile fabricated by ion exchange in glass. Our unique silver exchange technology provides non-toxic micro lenses having typical dimensions from 200 µm to 2 mm and excellent optical performance.

The single lenses have diffraction limited numerical apertures up to 0.5. The flat optical surfaces enable an easy assembly to micro-optical lens systems tailored to your specific requirements.

GRINTECH GmbH was founded in December 1999 as a spin-off of the Fraunhofer Institute for Applied Optics and Precision Engineering in Jena, Germany.
