Deposition Sciences Inc. (DSI)
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...See full product
