Dichroic Colour Filter for Photography

Photonics Buyers' GuideDichroic Colour Filter for Photography Does something look off to you? Does the colour look unnatural to you? Maybe that’s because you’re not using Knight Optical’s Colour Correction Filters. Knight Optical has successfully launched a range of Stock Dichroic Filters, for use within the Photography, Cinematography and Lighting Industries. Within the Photography and Lighting Industry, Dichroic Colour Correction Filters are designed to alter the overall colour of light in a system by adjusting the correlated colour temperature to display more naturally. Colour correction filters are typically temperature resistant and are available in either CTB (Colour Temperature Blue) or CTO (Colour Temperature Orange) types. CTB filters convert tungsten light to higher temperature daylight (and CTO filters perform the opposite, taking high temperature daylight and converting it to tungsten.

Knight Optical offers a range of temperature correction filters in both CTO and CTB types. We hold a massive inventory of Colour-correction filters, Long pass, Short pass, Band-blocking and Bandpass.
