Cemented Prism, Tir Prism Set, Beam Splitter Prism, Etc.
An optical prism is a transparent optical element formed by the intersection of two or more planes, which is usually used to change the propagation direction of light, disperse light (such as generating a spectrum), or achieve specific functions in an optical system. The main properties of a prism include its transparency, refractive index, and geometric shape. When light passes through a prism, it is refracted due to the difference between the refractive index of the prism material and the surrounding medium (such as air), thereby changing its propagation direction. In addition, a prism can also use internal reflection to change the path of light.
1. Glued prism
Product description
Glued prism is made of two or more prisms with different refractive indices bonded together by special optical glue. This design can eliminate chromatic aberration and aberration and improve imaging quality. Glued prism is widely used in optical instruments, medical equipment, laser systems and other fields.
Specifications
Material: Usually optical glass with high transmittance and low dispersion is used, such as H-K9, BK7, etc.
Dimensions: The external dimensions can be customized according to application requirements, generally ranging from 10 to 50 mm.
Angle tolerance: The angle tolerance is small, usually between 30′ and 3′, to ensure the accuracy and stability of imaging.
Coating: Anti-reflection film, reflective film, etc. can be coated as needed to improve transmittance and reflectivity.
2. TIR prism set
Product description
TIR prism set (Total Internal Reflection) uses the principle of total internal reflection of light at the prism interface to change the propagation direction of light. TIR prism group has the characteristics of compact structure, high transmittance and low loss, and is often used in laser scanning, projection display, optical communication and other fields.
Specifications
Material: Optical materials with high refractive index and low absorption, such as optical glass or special crystals.
Size: The specific size depends on the application requirements, such as the size range of DLP TIR prism group is 21.1×20.034×20mm.
Angle accuracy: The angle accuracy is high, usually within ±3′ to ensure accurate reflection and propagation of light.
Coating: AR film (anti-reflection film), high reflective film, etc. can be coated as needed to improve transmittance and reflection efficiency.
3. Beam splitter
Product description
Beam splitter is an optical element that can split incident light into two or more beams of light in a certain proportion. It is often used in spectral analysis, optical measurement, laser system and other fields. Beam splitter has the characteristics of high splitting accuracy, good stability and high transmittance.
Specifications
Material: Usually optical glass with high transmittance and low dispersion is used, such as H-K9L.
Dimensions: The external dimensions can be customized according to application requirements, generally ranging from 5 to 400 mm.
Split ratio: The split ratio can be adjusted according to requirements, such as the ratio of reflectivity to transmittance of a neutral splitter prism can be 1:1 or 2:8.
Coating: Polarized splitter film, anti-reflection film, etc. can be coated as needed to improve splitting efficiency and transmittance.
Wavelength range: The wavelength range of the splitter prism is wide, covering visible light to near-infrared bands.
