Right-Angle Prisms

Optics >>> Prisms >>> Right-Angle Prisms

Right-Angle prisms are commonly used to achieve a 90 or 180 light path bend.  Depending on prisms orientation, images will be inverted, but correct left-to-right.  If the prism is rotated 90, images viewed through the prism will be erected, but reversed left-to-right.  This prism can also be used in combination for image/beam displacement applications.
 

90 deflection

180 deflection

90 deflection occurs at the face.  The hypotenuse image is erected and reversed. 180 deflection uses with hypotenuse as the entrance and exit face.  The main application is as a retro-reflector provided that the plane of incident beam includes the vertex.
