Winner of R&D 100 Award for Segmented Tunable Filter

Segmented Tunable Filter

CPI's Segmented Tunable Filter received a prestigious R&D100 Award distinguishing it as one of the 100 most technologically significant products introduced into the marketplace in 2009. This electro-optical filter is an innovation capable of simultaneously collecting spatial and spectral information while providing high spectral resolution and rapid tuning. It dynamically sorts light into multiple discreet narrow spectral bands. Based on Fabry-Perot technology, this next-generation tunable optical filter achieves multiple, independently tunable filter segments on a single substrate. The patented technology is intended for use as the key dispersive element in hybrid multi-spectral imaging systems.
