Right Angle Prism

A Right-Angle Prism is a common optical component with the following characteristics: 1. Shape and Structure: It has a right-angled triangular cross-section, consisting of two mutually perpendicular right-angle faces and one hypotenuse face. It is typically made of transparent materials such as glass or quartz. 2. Optical Function: When light is incident perpendicularly on the right-angle face, it undergoes total internal reflection at the hypotenuse face, deflecting the light beam by 90° and achieving a change in the light path. If the hypotenuse face is coated with a reflective film, light beam deflection can be achieved through reflection even without meeting the total internal reflection conditions, and the light can be deflected by 180° (used as a retroreflector). 3. Wide Application: It is commonly used in laser beam steering, periscopes, optical interferometers, imaging systems, etc. It helps in compactly designing optical systems, reducing the space occupied by the light path, while maintaining the parallelism and intensity of the light beam. Due to its simple structure, stable performance, and high precision, the right-angle prism is widely used in the field of optics.
