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. 

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

We at GRINTECH support the GRIN technology with our long-standing technical expertise and reliable customer service.
