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.
