Short Wave-pass Filters

The short wave-pass filters has the advantages of wide cut-off band, deep cut-off depth, high conversion steepness and high transmittance. It can be widely used in fluorescence excitation spectrum measurement, Raman spectrum application, spectrum grouping application, astronomical observation application, etc. it can also be widely used in imaging optical system and machine vision system to eliminate interference light outside the available band, greatly improve the imaging clarity and the sensitivity of the system.
