What is a right angle prism?

A right-angle prism is an optical triangular blocks shaped like a right triangle a 90° apex angle.

It is commonly used to change the direction of the light path or to produce image inversion.

The prism can turn the beam of light through 90° by reflecting.

It has high precise surface quality and tight tolerance angles due to the characteristics of the right angle prism.

How does a 90° degree prism work?

An easy understanding of the principle is refraction and reflection.

When light enters one surface of a right-angle prism from the air, the light will undergo refraction and its direction will be slightly deflected and enter the interior of the prism.

When the light is in the inneral of the prism, it will accur the totally inneral refraction.

The reflected light will leave from another surface of the prism.

At this point, refraction occurs again, restoring the light’s propagation direction to that in the air, but the optical path has been changed in direction or flipped.

Why choose the right angle prism?

 

  • High reflectivity and low loss

There is almost no light loss because of the characteristics of the prism. It can reflect almost 100% light.

  • Flexible light path adjustment

The light can be redirected by 90° (reflected and reflected)

It can also reflect at a 180-degree angle (mirror reflection)

And also it can even achieve image flipping (left-right or up-down reversal)

It is suitable for imaging, scanning, and measurement systems.

  • Robust structure, easy to install

Compared with other prism , it is easy to use and install for the optical systems.

  • Durability and Stability

It has less effect to external dust, humidity or chemical corrosion, and its long-term stability is much better than other reflectors.
