Right Angle Prisms
Standard Right Angle Prisms
High Precision Right Angle Prisms
Nonstandard Right Angle Prisms
A right-angled prism is used as a mirror to deviate light by 90 degree, and also as a retroreflector to deflect light by 180 degree after the total internal reflection.
High efficiency, broadband beam turns
Turn a beam 90 or 180
Fused silica models transmit down to 200nm

90-degree Deflection
90-degree deflection occurs at the hypotenuse face.
The image is erected and reversed

180-degree Deflection

180 degree deflection takes hypotenuse as the input and output faces. Its main application is to be used as a retroreflector provided that the plane of incident beam includes the vertex.
