Product Description

Product Description

Product Description
Narrow-band interference filter is an optical device with a narrow bandwidth that allows light in a specific wavelength band to pass through and cuts off or reflects other short-wavelength wavelength bands. Ion-assisted deposition nanomaterials are evaporated in high vacuum, with good film density and high imaging clarity. Application areas: Fluorescence analyzer, microplate reader, cable TV upgrade equipment, wireless transmission equipment, mobile phone barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical equipment, infrared ink identification, red film identification
Features:
A narrowband interference filter is an optical device with a narrow bandwidth that allows light in a specific wavelength band to pass through and cuts off or reflects other short wavelength wavelength bands.

Our company's narrow-channel interference filters are made of multi-layer hard films by ion-assisted deposition of nanomaterials by high-vacuum evaporation, with good film density and high imaging clarity.
