optical filters

An optical element that blocks or transmits a selected wavelength of light. Optical filters can either be absorption filters or interference filters. Absorption filters absorb any unwanted wavelengths while the interference filter will use the effects of constructive and destructive superposition to transmit only the selected wavelength.
