What is an interference type 880nm Optical Longpass Filter?
A interference type 880nm optical longpass filter is a precision optical component that transmits near-infrared light above 880nm while blocking or reflecting shorter wavelengths below 880nm.This filter helps separate near-infrared signals from unwanted visible and ultraviolet light. It works well in applications that require clear near-infrared transmission and effective background light rejection.Common applications include machine vision and industrial inspection, fluorescence detection and biological imaging, infrared imaging and security systems, and laser beauty devices.
