Bandpass Interference Filters are used extensively in a variety of biotech, biomedical, and quantitative chemical applications to selectively transmit a narrow range of wavelengths while blocking all others. Interference filters are widely used in instrumentation for clinical chemistry, environmental testing, colorimetry, elemental and laser line separation, flame photometry, fluorescence, immunoassays, etc. In addition, interference filters are used to select discrete spectral lines from arc or gas discharge lamps (Hg, Xe, Cd, etc.) and to isolate a particular line from Ar, Kr, Nd:YAG, and other lasers. Interference filters are often used in conjunction with laser diodes and LEDs.

Bandpass Interference Filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. Notch Filters reject a portion of the spectrum, while transmitting all other wavelengths. Edge or Dichroic Filters transmit wavelengths that are either greater than the cut-on or shorter than the cut-off wavelengths. Color Substrate Filters utilize the material’s inherent adsorption and transmission properties, while ND Filters evenly reduce transmission across a portion of the spectrum.
