Color Optical Filters are often used as longpass or bandpass filters. Color Optical Filters are ideal for use as environmental displays, or for other machine vision or industrial applications. These filters utilize the material’s inherent absorption or transmission properties. By controlling the thickness of the material, precise filtering across large bandwidths can be achieved. Edmund Optics’ Color Optical Filters are available in glass, plastic, or film substrates. Glass filters offer high durability, while plastic or film filters are cost-sensitive alternatives.
Dichroic Optical Filters are used for color separation or color enhancement in machine vision or fluorescence applications. These filters can also be used as spectral beamsplitters. Dichroic Optical Filters are similar to Longpass Optical Filters or Shortpass Optical Filters, but ensure all rejected wavelengths are reflected. Edmund Optics offers a wide variety of Dichroic Optical Filters. Edmund Optics’ Dichroic Optical Filters have been designed for high reflectivity of unwanted color or wavelength ranges, while offering high transmission of remaining wavelengths.
