Prism is a polyhedron made of transparent materials (such as glass, crystal, etc.). It is widely used in optical instruments. Prisms are widely used to shift or deviate, and to transform or rotate images, or to separate light according to different wavelengths or polarized light. At the same time, many types of prisms use the characteristics of total internal reflection. The incident angle of light at the boundary between air and glass is greater than the critical angle (such as the critical angle of visible light in BK7 glass is about 42°), which will cause total reflection.

Yisu Photonics can divide prisms into several types according to their properties and uses. For example, in spectroscopic instruments, the composite light is decomposed into spectral "dispersion prisms", the more commonly used is an equilateral prism; the working principle of reflective prisms is actually the law of reflection and refraction of light. When light is reflected in the same medium, the reflection angle and the angle of incidence are equal; when the light is incident from one medium perpendicular to the two medium planes to another medium, it will not be refracted; the polarization beam splitter prism (PBS) generally consists of two right angles The oblique side of the prism is glued or glued, and the polarized beam splitter film is coated on the oblique plane, the P-polarized light in the incident light is transmitted, and the S-polarized light is reflected. All the light beams enter and exit the surface are generally coated with antireflection coating; there are many types of roof prisms, which are often used in imaging systems. According to customer needs, roof prisms, roof pentagonal prisms, roof prisms and Schmidt prisms can be provided. Light passing through a prism will generally deflect at a specific angle (such as 90°), and roof prisms are widely used in telescopes, optical systems, and rangefinders.

Huizhou Yisu Photonics has a mature prism processing technology and a complete prism processing production line for nearly 10 years. The types of prisms provided by our company include: right-angle prisms, equilateral prisms, pentagonal prisms, roof prisms, dove prisms, reflective prisms, Polarizing beam splitter prism, etc. According to customer requirements, different sizes and high precision optical prisms can be processed, and coating processing can be performed according to customer needs.
