An optical filter that transmits light according to wavelength, based upon wavelength interference at a filter surface.
A glass filter with a specially coated surface that restricts certain parts of thecolour spectrum. For example, when placed in front of a tungsten halogen light source(3200K), the colour temperature can be converted to 5600K (daylight).
A filter that reflects chosen wavelengths and transmits the remainder. It differs from gels as they absorb unwanted wavelengths.
A filter used to transmit light based on wavelength rather than on the plane of vibration. Dichroic filters will transmit one color while reflecting a second, when illuminated with white light.
An optical filter that transmits light selectively according to wavelength.
An optical filter that transmits light according to wavelength. Dichroic filters reflect light that they do not transmit. Used in bulk optics wavelength-division multiplexers.
A glass plate coated with a number of thin layers of material that will reflect all but one very specific colour. Also called dichroic mirror.
A dichroic filter or thin-film filter is a very-accurate color filter used to selectively pass light of a small range of colors while reflecting other colors. By comparison, Dichroic mirrors and dichroic reflectors tend to be characterized by the color(s) of light that they reflect rather than the color(s) they pass. (See dichroism for the etymology of the term.)
