Laser Filters are optical filters designed to transmit only a certain wavelength or range of wavelengths. Laser Filters are used to isolate certain wavelengths by reflecting or absorbing unwanted wavelengths. Laser Filters are offered in a wide range of designs, including Neutral Density, Dichroic, Bandpass, or Notch. Laser Filters are used in a large number of laser applications, as well as in microscopy. Some Laser Filters may also be used to transmit only certain polarization states.
