Popular science on the prism
The name is a color combination prism. The so-called color combination means that it can separate and sum light. There are four light-transmitting surfaces. White light can be taken in any one of the light-transmitting surfaces, and red and green can be emitted from the remaining three light-transmitting surfaces. The three primary colors of blue are the so-called three primary lights. This is spectroscopy. There is also light, that is, the three light sources of red, green and blue are taken in from any three transparent surfaces, and white light is emitted from the remaining surface. This is combined light. To put it plainly, red, green and blue can be combined into white, and white can be divided into red, green and blue. This is an important accessory on the projector. The reason why the projector can project colors on the screen, you should know that the colored light on the screen is composed of three primary colors, and the color combination prism is an important prism that forms the three primary colors.

The principle of color combination prism
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 different bands, it presents different colors in two directions. This dichroic principle is applied in the optical engine of the projector. Two dichroic beamsplitters are respectively coated with two different 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.
