Right Angle Prisms

Right angle prisms are usually used to turn the optical path or deflect the image formed by the optical system by 90 °. According to the different orientation of the prism, the imaging can be consistent from left to right and reversed from top to bottom, which is different from left to right. Right angle prism can also be used in image combination, beam offset and other applications.
Right angle prism: it is one of the basic functions of right angle prism to efficiently reflect the internal light by using the characteristics of critical angle.
