Harmonic prism is an optical element commonly used in projectors, which is based on the principle of combining three-color monochromatic light images to form a color pattern on the final screen. Structurally, it is made of prisms with different coatings that are bonded together, and because it is very durable and few people change it, the price will be slightly more expensive.
The role of the color-combining prisms is used to divide the light or make the beam of light dispersion, and its use is commonly used in the field of digital equipment, science and technology, medical instruments and other fields. Prisms are transparent materials, such as glass, crystal, etc., made of polyhedra, is an important optical element.
