Right Angle Prism  

 

The right-angle prisms are often preferable to an inclined mirror in applications involving severe acoustic or inertial loads. This is because a right-angle prism is easier to mount and deforms much less than a mirror in response to external mechanical stress. Very high transmission can be achieved by using the hypotenuse face in total internal reflection, and by antireflective coating the entrance and exit faces. Alternatively, the hypotenuse face can be used in external reflection, and coating with a metallic reflective coating.

A Right-Angle Prism is used as a mirror to deviate light through 90 degree, and also as a retroreflector to deflect light throgh 180 degree by total internal reflection.

 

90-degree Deflection

90 degree deflection occurs at the hyotenuse face.The image is erected and reversed

 

       

180-degree Deflection

180 degree deflection uses with hypotenuse as the entrance and exit face.The mail application of it is used as a retroreflector provided that the plane of incident beam includes the vertex.
