Right Angle Prisms Optical Right Angle Prism

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

on the entrance and exit faces. Alternatively,

the hypotenuse face can be used in external reflection,

and coating with a metallic reflective coating.
