WARNING
Potential hazards are not only related to direct
beams but also to reflected beams aimed at reflecting
surfaces such as prisms, windows, mirrors, metallic
surfaces etc.
Precautions:
Do not aim at areas that are essentially reflective, such
as mirror, or which could emit unwanted reflections.
