|Broad Band for Fluorescence Imaging and Machine Vision Applications||Narrow Band for
or Laser Clean Up
|OD 6.0 Blocking (<0.0001% Transmission)
OD 6.0 Filters are fabricated utilizing advanced Hard Coating technologies including ion beam sputtering (IBS) and magnetron sputtering, guaranteeing high transmission, deep blocking, and extended lifetimes.
|OD 4.0 Blocking (<0.01% Transmission)
OD 4.0 Filters are typically manufactured utilizing high volume Hard Coating technologies, guaranteeing high transmission, deep blocking, extended lifetimes, and generous volume discounts.
|OD 2.0 Blocking (<1% Transmission)
OD 2.0 Filters are typically manufactured from traditional evaporative coating technologies, or absorptive colored glass, yielding cost effective filters.
Bandpass Filters are used to selectively transmit a portion of the spectrum while rejecting all other wavelengths. 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 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. 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. Bandpass Filters are angular sensitive, so care should be taken when mounting or integrating into an optical system.
