CLZ Optical offers a range of high-quality longpass filters in stock. These filters, also known as edge filters, are essential in applications where the elimination of unwanted wavelengths is critical.

Our product line includes infrared longpass filters and dichroic longpass filters, designed to meet specific requirements for edge cutoff, transition steepness, and transmission or blocking performance. They can be widely used in fluorescence excitation spectroscopy, Raman spectroscopy, spectral grouping, and astronomical observation applications. They are also widely used in imaging optics systems and machine vision systems to eliminate interfering light outside the usable wavelength range, improving image clarity and system sensitivity.

In addition, CLZ Optical provides customized optical filters tailored to various dimensions and specifications, ensuring versatility for a wide range of applications.
