The ios™ Optics competitive advantage stems from our service oriented culture and nearly 40 years of fabrication experience.

NIKKOR lenses are born from a tradition of elite craftsmanship and a pursuit of optical perfection more than 80 years in the making.

An optical homogenizer provides highly uniform or homogenized illumination.  Through TIR (total internal reflection), a lightpipe can transform the input of non-uniform light sources into highly uniform (homogenized) light.  Our expertise in manufacturing rectangular, tapered and octagonal lightpipes with extreme tolerance requirements in Scratch-Dig, Surface Figure, Chip and parallelism has allowed us to become the premier lightpipe vendor for some of the world’s most demanding applications.
