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 or lithium ion exchange process in glass. Our unique rod micro lenses have typical dimensions from 250 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.
