The dichroic beam splitter is the dichroic element in the MD projector. A spectroscopic film is plated on the substrate glass, and a white light source is irradiated on the dichroic spectroscope. Part of the band of light is reflected and part of the band of light is transmitted. Because of the bands, it presents colors in two directions. This dichroic principle is applied in the optical engine of the projector. Two dichroic beamsplitters are respectively coated with two beamsplitter films to decompose white light into R, G, and B primary colors. The principle of dichroic light splitting can also be used to make a color prism, which combines the three primary colors to Form a color image
This is one of the most important accessories on the projector, the projector is able to cast shadows of color on the screen, you should know what color light is composed of three primary colors on the screen, color important Prism Prism is Formed of three primary colors.
