Optics: Optical Filter

Optical filters are used to selectively transmit one wavelength or a range of wavelengths, or to block transmission. Optical filters are used in applications such as fluorescence microscopy, spectroscopic analysis, clinical chemistry, and machine vision inspection. Optical filters are ideal for life sciences, imaging, and industrial fields. Edmund Optics offers a variety of optical filters for numerous applications, including bandpass, notch, edge, dichroic, color glass substrates, and ND filters. Edmund Optics also provides high-durability hard coatings for applications that require high optical density and maximum performance.
