Request InfoDeposition Sciences Inc. (DSI)DSI’s photolithography capability produces patterned thin film coatings (including bandpass filters, absorption coatings, and metals) on substrates up to 6 inches. DSI’s processes enable high placement accuracy, the ability to accurately maintain coating spectral properties at the smallest geometries, and two-sided patterning capabilities (for flat windows and filters). DSI utilizes both wet and dry film resist processes to support the development and production of challenging patterned coating geometries for our customers. Our positive and negative resist photolithography...See full productRelated content from Photonics MediaPRODUCTSPromoted Content October 2022 IssueIR FiltersDSI designs and manufactures thin film coatings such as bandpasses, beamsplitters, ARs, and absorption coatings for use in the MWIR thru LWIR wavelength regions.

They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass.
