The pentagonal prism uses the reflection of two surfaces to make the beam deviate by 90 ° while maintaining the parity of the image. The deviation of the beam does not change the slight rotation of the prism, so it is very useful for applications requiring strict alignment. The alternative prism configuration includes a roof pentagon that reverses the parity of the image and a half pentagon that deflects the light 45 °. The pentagonal prism is usually used in image installation components and as a laser insertion prism for advanced monitoring and ranging applications.
Generally, aluminum, silver and gold mirror coatings and epoxy protective paint are used on the two reflecting surfaces of the pentagonal prism. In addition, the 22.5 ° incidence angle of the reflecting surface is very suitable for the coating of dielectric high reflector and dichroic spectroscope working at a wide cone angle.
Hanzhong Borisun Optics offers you a variety of options for standard and customized pentagonal prism configurations, which have excellent beam alignment, image clarity and appearance quality. Laser/broadband antireflective coating can be used for the incident/outgoing surface, and the protected metal and customized dielectric coating can be used for the reflective surface. A pentagonal prism can also be bonded with a wedge prism or other components to create optical components. Suzhou Xixian Optoelectronics is a professional optical component manufacturer, which can be customized according to user needs.
