Notch Filters
Deposition Sciences Inc. (DSI) DSI designs and manufactures notch and bandpass filters, beamsplitters, ARs and absorption coatings for use in the VIS to the MWIR wavelength regions, customized to specific requirements. Using photolithography, we can also pattern these coatings with feature sizes as small as 20 µm to define apertures, segments and/or fiducials.
