Interference band pass filters are relatively inexpensive wavelength selectors that allow transmission of a pre-determined 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, etc.
Optometrics Corporation produces thousands of filters specified by and designed for other instrument manufacturers. If their standard filters do not conform to your requirements, Optometrics can design and manufacture filters to your performance and dimensional specifications.
In addition to interference filters we are pleased to offer diffraction gratings, wire grid polarizers and monochromators.
