Right-Angle Prism
BK7 | Fused Silica | Laser grade
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.
