Original caption: "Barr Associates Developed Advanced Image Quality Space-Qualified Ultraviolet Interference Filter

Under a Small Business Innovation Research (SBIR) contract to Jet Propulsion Laboratory, Barr Associates developed advanced image quality space-qualified ultraviolet (UV) interference filters. To fabricate the filters, Barr developed an advanced ion-assisted deposition process, which enabled creation of filters that eliminated certain technical problems and broadened the range of environments in which the filters could be used. Barr refined the process and uses it in a commercial line of filters that have utility in such applications as fiber optic communications, hand-held spectrometers, and a variety of industrial applications. The filters are stable, durable, provide high spectral performance, and can be fabricated in miniature for portable instruments."
