Stage Lighting Custom Optical Filters Dichroic Mirror Interference Filter

Stage Lighting Dichroic Mirror RGB Combiners with Reflectivity over 97%

Description

A dichroic filter, thin-film filter, or interference 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 colors of light that they reflect, rather than the colors they pass.

The dichroic mirrors for stage lighting produced by HTOE (also known as combiners, semi-reflectors, laser beam splitters, laser beam splitters or RGB combiners) are widely used in the fields of projectors, optical instruments, laser equipment and scanners. The dichroic mirror has high reflectivity to the beams below the cut-off wavelength and high permeability to the beams above the cut-off wavelength. The dichroic mirror is manufactured according to customers' requirements.

Principle

Dichroic filters use the principle of thin-film interference, and produce colors in the same way as oil films on water. When light strikes an oil film at an angle, some of the light is reflected from the top surface of the oil, and some is reflected from the bottom surface where it is in contact with the water. Because the light reflecting from the bottom travels a slightly longer path, some light wavelengths are reinforced by this delay, while others tend to be canceled, producing the colors seen.
