Right-Angle Prism

Manufacturer's part number :


Manufacturer Altechna


Description :

Right angle prisms are used to direct beams at 90 degrees by using the hypotenuse face for total internal reflection (TIR). These 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 mirrors in response to external mechanical stress. As long as acceptance angle limitations for TIR from the roof faces are not exceeded, the right angle prism can also serve as a retroreflector, reflecting a beam back.
