Can work as internal or external reflectors or as retro-reflectors
Various dielectric coatings can be deposited upon request
These prisms are used to direct beams at 90 degrees by using
hypotenuse face in total internal reflection (TIR). Right angle
prisms are often preferable to an inclined mirror in applications
involving severe acoustic or inertial loads, because they are
easier to mount, and deform much less than mirror in response
to external mechanical stress. As long as acceptance angle
limitations for TIR from the roof faces are not exceeded, the right
angle prisms can serve as a retro reflector, turning beams back to
the original direction.
