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.
