    Bandpass Filters

    Optical Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. Optical Bandpass Filters are ideal for a variety of applications, such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging. These filters are typically used in the life science, industrial, or R&D industries.

    Edmund Optics offers a wide variety of Optical Bandpass Filters in a range of bandwidth options. Laser Line filters typically have narrow bandwidths of 2 – 5nm for demanding laser applications. Fluorescence Filters, which have been designed to maximize the energy of the excitation and emission bands, typically have broad bandwidths of 20 – 70nm. Edmund Optics’ 10nm filters are ideal for chemical, environmental, or elemental analysis. Hard coated filters offer maximum performance with exceptional durability. Traditionally coated evaporated filters are cost-sensitive alternatives. Optical Bandpass Filters are angular sensitive, so care should be taken when mounting or integrating into an optical system.
