The filters used by fluorescence detection systems are arguably the most important element defining the system performance. Alluxa’s new line of thin substrate ultra-flat dichroics and polychroic filters provide improved optical performance, achieve near zero net stress on the primary coated side, and require only a simple AR coating on the back. Eliminating backside compensation lowers costs, improves transmission levels, reduces scatter and improves transmitted wave-front. Flatness levels of < 0.1 waves RMS at 632 for a one inch part are achievable at thicknesses ranging from 0.5mm and above. These new polychroic filters are built with fully dense, hard coated refractory oxides using a proprietary high speed plasma deposition technology purpose built for the challenges presented by the latest optical instruments of the life sciences industry.
