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.
