Deposition Sciences Inc. (DSI)Request Info
DSI designs and manufactures thin-film coatings such as bandpasses, beamsplitters, ARs and dark mirrors for use in the MWIR thru LWIR wavelength regions. The coatings are produced by either sputtering or evaporation, and can be applied to substrates as large as 8 inches in diameter. Substrates include Ge, Si, ZnS, ZnSe, Quartz, and Sapphire.
Our positive and negative resist photolithography processes enable two-sided patterning of these coatings with feature sizes as small as 20 µm. With our well-equipped metrology lab, we can measure spectral performance over operating tempertures as low as 15 K and as high as 353 K, perform a wide range of Mil-Spec environmental tests, and precisely measure surface figure both before and after coating.
Applications include atmospheric/remote sensing, medical/environmental monitoring and gas detection, as well as targeting/tracking. DSI’s optical thin films and patterns are custom-designed for specific applications. Our engineers work closely with customers to design the optimal combination of performance, delivery, and cost.
