Long Wave-pass Filters

PRODUCT CATEGORIES

INOUIRY

The long-wave filter is made of UV fused quartz substrate, and has the advantages of wide cut-off bandwidth (from deep UV to specified cut-off wavelength), deep cut-off depth, high conversion steepness, high transmittance, etc. It can be widely used in fluorescence excitation spectrum measurement, Raman spectroscopy, spectrum grouping and astronomical observation. It can also be widely used in imaging optical systems and machine vision system applications to eliminate interference light outside the available band, improve imaging clarity, and improve system sensitivity.
