Bandpass Filters

Bandpass Filters

A bandpass filter is a relatively inexpensive type of optical filter used as a wavelength selector that allows transmission of a predetermined wavelength while rejecting or blocking other wavelengths.

Applications for a bandpass filter include, but are not limited to:

  • Clinical chemistry instrumentation
  • Environmental testing
  • Colorimetry
  • Elemental and laser line separation
  • Flame photometry
  • Fluorescence
  • Immunoassays

Along with our wide selection of standard bandpass filters, we design and manufacture optimized solutions for instrument manufacturers world wide.
