Bandpass Interference Filter

Whether your application is in biotechnology, R&D, Test and Measurement, Machine Vision or Analytical Instrumentation W2 has optical filters capable of meeting your needs. From optical bandpass and optical edge filters to notch and optical neutral density filters, EO’s selection of standard optical filters and custom optical filters are optimized for your requirements.

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.
