What is a BK7 Penta Prism?

A N-BK7 Penta Prism is a five-sided optical prism made from high-quality BK7 glass.

It is designed to deviate incoming light by 90° without inverting or reversing the image.

And the BK7 Penta Prism provides stable and accurate light reflection.

Therefore,it is ideal for optical measurement, imaging, and laser applications.

The Chenyu pentaprism is made of high-quality N-BK7.

Also, it can be used in various visible light applications. There are multiple sizes to choose from.

Advantages of N-BK7 Penta Prism

  • Stable 90° optical deflection

The BK7 penta prism can deflect the incident light by 90°. And the deflection angle will not change with the rotation of the prism, ensuring the stability of the optical path.

  • High optical transmittance

Using high-quality BK7 optical glass, it has a high transmittance in the visible light band and low optical loss.

  • Excellent optical accuracy

The precise polishing surface and strict processing tolerances ensure that the beam deflection is accurate.

  • Durability and long-term stability

The structure is stable. Therefore,  it is suitable for long-term use in industrial applications.

Applications of N-BK7 Penta Prism

  • Optical Measurement and Alignment

The penta prism is more suitable in laser alignment systems, optical surveying, and precision measurement instruments than other common prisms.

  • Laser and Photonics Systems

Guides and redirects laser beams while maintaining beam integrity.

  • Imaging and Camera Viewfinders

Also, people usually choose it in single-lens reflex (SLR) cameras to correct image orientation and provide accurate viewfinder display.

  • Scientific Research and Education

People can use it to search the light reflection and beam deviation.

  • Industrial Automation and Sensors

Applied in optical inspection, industrial sensors, and automated vision systems.

The Chenyu BK7 penta prism is an optical tool using to define right angles, featuring a 90-degree deviation in light.
