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.
Advanced Materials – Sputtered Thin Film 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 Material
DSI’s Sunshade is the world’s best thermal control material for use in LEO, MEO and GEO. Thermal control coupled with ESD and RF Transmissive properties..
Short Wave Pass Filters & Long Wave Pass Filters
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.
Dichroic Edge Pass Filters
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 Coatings
Sputtered Coatings – Temperature & Humidity Stable PRODUCT OVERVIEW DSI’s photolithography capability enables production of patterned thin film coatings (including bandpass filters, absorption coatings, and
