Interference bandpass filters are relatively inexpensive 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, etc.

Designing and producing interference filters is a complex procedure requiring thin-film expertise and sophisticated instrumentation.

Optometrics LLC produces its filters in-house on customized vacuum systems, operated by a staff of experienced technicians.


We manufacture interference filters with central wavelengths from 337 nm to 1.064 microns in various sizes ranging from 12.7 mm diameter up to 50 mm square and two levels of blocking.


This allows you to select the most economical filter that meets your optical performance criteria.
