For the protection or control of dangerous zones with openings on several
sides, deflection mirrors can be used.
If emitted light must be deflected with a 90° angle, the mirrors surface and
the beam’s path must form a 45° angle.
The figure below shows an application using 2 deflection mirrors in a "U"
shape configuration.
Instructions for mirrors use:
•
Mirrors should be installed in such a way that the minimum
calculated safety distance S is achieved on each side of the
perimeter (see figure 14).
•
Total lenght of the perimeter should be smaller or equal to the
scanning range taking into account the attenuation due to mirrors
(expect a 10% decrease on the scanning range per added mirror).
•
Optical alignment of the emitter unit, the receiver unit and mirror(s)
must be carefully carried out.
• It is recommended to use a maximum of 3 mirrors.
