Righ
angle prisms
Prisms are, essentially, blocks of optical material with flat polished
sides that are arranged to be at precisely controlled angles to each
other. They can be used to deflect, deviate and rotate beams of light
as well as dispersing their wavelengths. There are many types of kkrism,
each having a particular geometry to achieve the reflections necessary
to perform a specific imaging task. The most important to the prism
is the angular specification of prism. |
Right angle prisms are used to deviate beam through 90°, when beam
enters normal to right sides, and as also a retroreflector to deviate
beam through 180° when beam enters normal to hypotenuse. |
