the types of optical prism and what should be paid attention to in its application?

Optical prism In optical devices, a piece of glass or other transparent material cut at a precise angle and plane can be used to analyze and reflect light. Ordinary triangular prism can separate white light into its constituent color, which is called spectrum. Each color or wavelength of white light is bent or refracted, but the number is different. The shorter wavelength (towards the purple end of the spectrum) bends more, while the longer wavelength (towards the red end of the spectrum) bends less. This prism is used in some spectroscopes, instruments for analyzing light and determining the identification and structure of materials emitting or absorbing light.

Optical prism refracts light to reflect (reflection prism), disperse (dispersion prism) or split beam (beam splitter) light. Prisms are usually made of glass, but any material can be used as long as the material is transparent and suitable for the design wavelength. Common materials include glass, plastic and fluorite.

Optical prisms can reverse the direction of light through internal reflection, so they are very useful in binoculars.

Depending on the application, optical prisms can be made into many different forms and shapes. For example, the Polo prism is composed of two prisms, which can reverse both images and images, and is used in many optical observation instruments, such as periscope, binoculars and monocular telescopes.

Prism is a polyhedron made of transparent materials, mainly made of glass and crystal, and is composed of two intersecting polishing planes at a precise angle. It can turn or deviate from the light, invert or rotate the image, decompose the composite light into spectrum and separate the polarization state. At present, the application of prism is very common, ranging from life to high technology, and in the optical industry, the application of prism is also very common. Let’s see what should be paid attention to in the application of optical prism?

In the optical industry, prisms can be divided into many types according to their properties and uses. For example, in spectral instruments, those that decompose composite light into spectra are called dispersion prisms, and in periscopes, binoculars and other instruments, which can change the direction of light, thus adjusting its imaging position, are called total reflection prisms; The commonly used right-angle prism, which has the function of light reflection, is often the substitute of the transmitting mirror and the reflector of the small optical system; Like a hollow reflector, a pyramid prism has the function of light return, and is often used for reflectors such as interferometer or distance meter; The equilateral dispersion prism is mainly used to separate the wavelength, and is often used for spectrometer measurement, and for light dispersion compensation; Like Dowell prism and pentagonal prism, they all have their own special effects, which are used to rotate or reverse the image. The 90-degree benchmark of the inkjet is realized by using this principle of prism.

Prisms can be divided into many types according to other uses, properties, shapes, etc. Different prisms have different uses. When you use them, you must understand the properties of different prisms and choose the right prism according to your desired effect.
