Product Features:
Narrowband interference filter is an optical device with a narrow bandwidth that allows light in a specific wavelength band to pass through while cutting off or reflecting other short and long wavelength bands
Our company's narrow channel interference filter is made of multi-layer hard film deposited with ion assisted nano materials by high vacuum evaporation, with good film density and high imaging clarity.
Application fields:
Fluorescence analyzer, enzyme-linked immunosorbent assay (ELISA) reader, cable TV upgrade equipment, wireless transmission equipment, mobile barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical instrument, infrared ink recognition, red film recognition, facial recognition sensor system. Handheld infrared laser rangefinder, laser rangefinder, optical instrument, medical and health equipment, and detection instrument.
