Right Angle Prism
| Right Angle Prism may be used as a 90 degree reflector or 180 degree
retroreflector. The prism deflect, deviate and rotate beams of light
as well as dispersing their wavelengths. They usually used for beam
deviation or as substrates for beamsplitters. |

| Note: The general tolerance specifications above provide
a guideline regarding manufacturing capabilities for optics ranging
in size from 3.2-76.2mm. The manufacturing limits are not absolute;
tighter tolerances may be possible. Part specific tolerances may
vary depending on component size, shape, and/or material. |
