Interference Filters

Interference Filters

Interference filters are relatively inexpensive types of optical filters used as wavelength selectors that allow transmission of a predetermined wavelength while rejecting or blocking other wavelengths.
Interference filters are widely used in:

  • Instrumentation for clinical chemistry
  • Environmental testing
  • Colorimetry
  • Elemental and laser line separation
  • Flame photometry
  • Fluorescence
  • Immunoassays

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