Bandpass Filters with FWHM 10 nm

Infrared Bandpass Filters

A bandpass filter is an inexpensive optical filter used as a wavelength selector that allows transmission of a predetermined wavelength while rejecting or blocking other wavelengths. Along with our wide selection of standard infrared filters, Optometrics designs and manufactures custom bandpass filters for instrument manufacturers world wide.

Optical Bandpass Filter – Typical Transmission Curve

Bandpass Filter Terminology

Transmission Curves are graphs or mathematical functions that characterize optical filters. Typically expressed as the percent or fraction of light transmitted versus wavelength.

  • Bandwidth is a range of wavelength that specifies the transmitted part of the spectrum.
  • Central Wavelength (CWL) is the midpoint wavelength of the bandwidth.
  • Peak Transmittance is the maximum percentage of light transmission through the filter. It is often centered at the CWL, but many filters have fairly flat transmittance across the bandwidth.
  • Half Bandwidth (HBW) or Full Width-Half Maximium (FWHM) is the wavelength range that characterizes a bandpass filter. It is bound by the wavelengths where transmittance is half (50%) that of the peak transmission.
  • Upper and Lower Blocking Regions are the ranges of wavelengths where the light is attenuated.
