In astronomical observations, optical filters are able to provide the wavelength selectivity needed to enable telescopes to discriminate signal from background information. These filters often require larger sizes, higher uniformity, and excellent surface quality and surface figure.
Iridian Spectral has designed and manufactured filters and provided coatings on optical components for satellite and low-earth orbit earth observation instruments and for earth-to-orbit (or beyond) optical communications.
Iridian Spectral offers a variety of filters for these earth and stellar observation and communications applications including:
