DSI utilizes its own, proprietary version of magnetron sputtering technology known as MicroDyn® This page lists the different types of optical coatings we produce, although there are virtually limitless variations on each of these. We invite you to discuss your particular coating needs with our engineering staff so that we can develop a product which is best suited for your specific application, considering all aspects of optical performance, environmental factors, and cost.
Flexible Sputtered Coatings
DSI’s extensive experience in developing coating methods for flexible coatings allows us to create complex coatings using a wide range of materials on a broad selection of substrates. Learn More
Sunshade Thermal Control
DSI’s Sunshade material delivers efficient heat management, while also accommodating the increased demand for high speed data transmission in current satellite technology.
Long/Short Wave Pass
DSI edge filters are distinct from bandpass and notch filters in that they either pass wavelengths above (long wave pass) or below (short wave pass) a given single wavelength value.
Bandpass Filters
DSI designs and manufactures bandpass coatings for use at wavelengths ranging from the ultraviolet through the long-wave infrared, including broad bandpass, narrow bandpass and dual bandpass filters.
Dark Mirror Coatings
DSI dark mirrors or absorbing coatings are distinguished by their broadband spectral performance and exceptional environmental durability. Their use ranges from visible through longwave infrared spectral regions.
Notch Filter
DSI has extensive experience in the design and manufacture of notch filters for use ultraviolet wavelengths through the long-wave infrared. These include broad and narrow notch designs.
Beamsplitters
DSI custom manufactures a wide variety of plate type beamsplitters, including polarizing and non-polarizing designs, for use in the ultraviolet, visible, and infrared spectral regions.
Edge/Dichroic Beamsplitters
DSI custom manufactures a wide selection of edge filters for use at wavelengths ranging from the ultraviolet through the long-wave infrared, distinguished by excellent durability with no wet/dry shift.
Patterned Thin Film Optical Filters
Heat-Resistant Optical Coatings PRODUCT OVERVIEW DSI’s photolithography capability enables production of patterned thin film coatings (including bandpass filters, absorption coatings, and metals) on substrates up
