Approximation and Application of Penta prism

[Abstract]:
Penta prism uses the reflection of two surfaces to deflect the beam 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 useful for applications that require strict alignment.

Penta prism uses the reflection of two surfaces to deflect the beam 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 useful for applications that require strict alignment. Alternative prism configurations include roof pentagons that reverse the parity of the image and half pentagons that deviate the light by 45°. Penta prism is commonly used in image mounting components and as a laser insertion prism for advanced surveillance and ranging applications.

Penta prism

Usually, mirror coatings of aluminum, silver and gold and epoxy protective paint are used on the two reflective surfaces of Penta prism. In addition, the 22.5° incident angle of the reflective surface is very suitable for dielectric high-reflection mirrors and dichroic beamsplitter coatings that work under wide cone angles.

We are happy to provide you with a diverse selection of standard and custom Penta prism configurations, which have excellent beam alignment, image clarity and appearance quality. Laser/broadband anti-reflective coatings can be used on the entrance/exit surface, and protected metals and customized dielectric coatings can be used on the reflective surface. Penta prism can also be glued with wedge prisms or other components to create optical components.

With our state-of-the-art metering equipment and custom tools, Penta prism can accurately measure the accuracy of the 90-degree azimuth beam deviation. Our high-end goniometer supports advanced modern detection technology. Our laser interferometer combined with precise customized optical and mechanical fixtures can achieve the highest resolution Penta prism measurement.
