Borosilicate Coating Dichroic Optical Filter BK7 Bandpass Filter Custom

High Quality Borosilicate Coating Bandpass Dichroic Optical Filter

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 thematerial’ s inherent absorption or transmission properties.By controlling the thickness of the material, precise filtering across large bandwidths can be achieved.GIAI photonics Color Optical Filters areavailable in glass, plastic, or film substrates.Glass filters offer high durability, while plastic or film filters are cost-sensitive alternatives.
