Classification and use of prisms

When you lift a prisms, you will think of a colorful picture. This is because the prism is formed by processing transparent optical glass. Each prism works by refracting light together with the reflecting surface. And the prism is processed by a variety of processes, mainly including forming blank, milling, fine grinding, polishing, edging, cleaning, inspection, coating, etc. The prism can divide the light into different components, and can also be used to reflect or polarize the light. The refractive index of most media is related to the color of the light wavelength. When the light passes through the prism, the light has different degrees of color separation due to the dispersion of the prism after the refraction. Due to the particularity of prism manufacturing and light refraction, what are the classifications of prisms? What are the specific uses?

Prism is a polyhedron made of transparent material and is an important optical element. The plane where the light enters and exits is the side, and the plane perpendicular to the side is called the main section. Prisms can be divided into right-angle prism, dispersion prism, right-angle triangular prism, pentagonal prism, Dawey prism, right-angle ridge prism, rhombus prism, PRO prism, light cube prism, equilateral triangular prism, wedge prism, special-shaped prism, etc.

A right-angle prism is generally a prism whose cross section is a right-angle triangle. It is often used to replace a plane mirror in optical instruments to change the direction of light transmission, with less energy loss and better effect.

Dawey prism can also be said to be a cut right angle prism, which not only reduces the weight of the prism, but also reduces the internal reflection of the stray light of the prism. When used for the condensing beam, it will cause astigmatism and polarization of the beam, so the collimated beam will be used for the condensing beam.

The dispersion prism is mainly used to decompose the components of light and make the light present its original color. Due to the influence of the frequency of light on the refractive index, when the white light of different frequencies enters the prism, the light wave of different frequencies will deflect to different degrees. The blue light is slower than the red light, so its deflection is more than the red light.

Prisms can change the direction of the beam without changing its concentration and dispersion. Different prisms have different effects on the light and different uses.
