Nano-post lens arrays replace absorbing color filters to separate wavelengths in image sensors while increasing manufacturable feature width.
Vary furnace heat and drawing speed in multilayer polymer preforms to produce thin, flexible filters with tunable spectra.
High-angle world light is filtered before the cross coupler, reducing distracting flares while preserving in-view light.
A holographic waveguide routes light between zones by wavelength and orientation, helping integrate sensors and displays with less bulk in smart eyeglasses.
See how layered color-filter and transparent optical elements balance light direction control with efficient extraction of a target wavelength.
