Product Case Studies

A pentagonal prism deflects the incident beam or image by 90 degrees without generating inverted or reversed images. In addition, a 90 ° beam deflection does not require precise alignment of the prism with the incident beam or image.

Optical prisms are used to redirect light at a specified angle. Optical prisms are an ideal choice for light deviation or adjusting image direction. The design of optical prisms determines the interaction between light and light. When light enters an optical prism, it reflects off a single surface or multiple surfaces before leaving, or refracts as it passes through a substrate. Prisms are widely used in laser research, laser optical systems, optical imaging, machine vision, life sciences, biomedicine, and other fields or products.

The structure of a pentagonal prism consists of five faces, two of which are used as reflective surfaces, while light enters and exits from the other two faces. When light enters a prism, it first reflects on one reflective surface, then reflects on a second reflective surface, and finally exits the prism from the exit surface. These two reflections work together to flip the image (upside down) while keeping its vertical position unchanged.

characteristic

• • Image flipping：A pentagonal prism can achieve left and right flipping of an image without affecting its vertical orientation, which is crucial for optical systems that require maintaining the correct viewing direction.

• • high-quality images：Due to the fact that light is mainly transmitted through reflection rather than refraction, dispersion and other optical distortions can be reduced, maintaining high-quality images.

• • Compact design：The structure of a pentagonal prism is compact and suitable for use in optical systems with limited space.

application

• • telescope：In monocular and binocular telescopes, pentagonal prisms are used to correct the observed image, making it consistent with the actual situation and providing the correct observation direction.

• • camera：In some specially designed cameras, a pentagonal prism is used to correct the image seen through the viewfinder to align with the direction of the captured photo.

• • Optical measuring instruments：In optical measuring instruments that require precise image orientation, pentagonal prisms are used to maintain the correct orientation of the measured image.

advantage

• • Provided an effective image flipping method suitable for various optical applications.

• • Due to mainly transmitting light through reflection, it can reduce dispersion and optical distortion, and maintain image quality.

• • Compact structure, suitable for designs with limited space.

In short, a pentagonal prism is a very useful optical element in specific optical applications, which, through its unique structure and working principle, can achieve effective image flipping while maintaining high-quality image output.
