Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. We offers a wide variety of Bandpass Filters in a range of bandwidth options for ultraviolet (UV), visible (VIS), or infrared (IR) applications. 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.
Bandpass 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. Bandpass Filters are angular sensitive, so care should be taken when mounting or integrating into an optical system. For convenience, many of our filters are also available in kits.
