Right-Angle Prisms - Retroreflectors
Working as internal or external reflectors or as retro-reflectors
Various dielectric coatings can be deposited upon request

Right-angle prisms - retroreflectors 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 are working as a retro reflector, turning beams back to the original direction.
