Description

The Gradient Index (GRIN) lenses by Altechna are purposefully designed for particular working distances. GRIN Lenses are easy to carry and integrate into visible systems.

The product is offered with 0.25 and 0.23 pitch GRIN lenses. The 0.25 pitch lenses are suitable lenses for beam colimation of optical fibers or laser diodes, due to their 0 mm working distance. The 0.23 pitch lenses are also the suitable option for lenses that cannot be contacted and for focusing purposes, enabled by their small working distance.

The model also provides lenses with one 8° wedged face with wide band anti-glare covering and BBAR coating. The GRIN lenses have a slant-end surface which decreases back reflections. In addition, customizing GRIN lenses by request is allowed.
