Product Description

Introduction to High Quality Long Wave Pass Filter:

The long wave pass filter provided by Horse Optics has the advantages of steep cutoff band, deep cutoff depth, high conversion steepness, and high transmittance. It can be widely used in fluorescence excitation spectroscopy measurement, Raman spectroscopy application, spectral grouping application, astronomical observation application, etc. It can also be widely used in imaging optical systems and machine vision system applications to eliminate interference light outside the available band, greatly improving imaging clarity and system sensitivity.
