Shortpass filters provided by Grand Unified Optics feature wide blocking bandwidth, high blocking depth,high transmission and high blocking slope. Widely used in fluorescence excitation spectrum measurement, Raman spectrum, spectral group, astronomical observation application etc., they are also be widely used in imaging optical systems and machine vision systems to eliminate interfering light whilst improving the imaging quality and sensitivity of the system. When standard shortpass filters are combined with our standard longpass filters, they can be used to set up variable bandwidth bandpass filters system. (We also provide standard filter mounted rings which can easily be to used to connect different filters based on the standard screw thread.)
