Rejection Band Filters

Precision optical filters since 1969, from UV to NIR. We specialize in custom filters from prototype to OEM quantities. Fluorescence, astronomy, and overrun filters in stock. Prototyping, engineering, and high-volume production utilizing plasma-assisted reactive magnetron sputtering, e-beam, thermal evaporation, and ion assist. ISO 9001:2015 Certified.

Designer and manufacturer of interference filters: narrow and broad bandpass, long- and shortwave, ND filters, atmospheric windows, AR and metallic coatings. Holographic diffraction gratings: plano, concave and blazed, pulse compression/stretcher gratings. WDM and telecom applications include diode laser tuning gratings and network communications gratings.

Deposition Sciences, Inc. (DSI) produces a wide variety of highly durable and heat-resistant optical coatings. Our technologies and customer deposition chambers offer coatings in the visible (VIS) near-infrared (NIR), shortwave infrared (SWIR), and midwave infrared (MWIR) spectral wavelengths. ISO 9001:2015 certified.
