Color and Absorptive Filters are available in longpass, bandpass, and neutral density options. Color and Absorptive 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, rather than interference effects from thin film coatings. By controlling the thickness of the material, precise filtering across large bandwidths can be achieved. Edmund Optics’ Color and Absorptive Filters are available in glass, plastic, or film substrates. Glass filters offer high durability, while plastic or film filters are cost-sensitive alternatives.
