Band Pass Filter

A high-transmittance bandpass filter that selectively allows light of specific wavelengths to pass through

This glass features an optical thin film coating that selectively transmits or reflects light at specific wavelengths.
It is used as a wavelength-selective transmission filter in measurement instruments, such as automotive LiDAR systems and pulse oximeters.

Applications

  • LiDAR
  • Facial recognition system
  • Inspection and analytical equipment

Features

  • Low angle dependency
    The shift in the center wavelength is minimized compared to a typical bandpass filter.
  • High transmission, narrow bandwidth, and high blocking performance
    This filter effectively eliminates unwanted wavelengths, contributing to high-precision measurements.
  • Customizable transmission wavelength bands
    Specific wavelengths can be transmitted or blocked according to the requirements of your application.
