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.
