Fig. 19 Application example for the penetration of panes of glass
If reflectors are mounted on glass walls, there is a danger that the glass and not the reflec-
tor will reflect the beam. This situation may only occur after commissioning if the glass
wall moves slightly. However, it does not occur if the beam strikes a glass wall at an angle
greater or less than 90°.
Recommendation: In such cases hit the beam in a light angle of 5° – 10° to the reflector,
in order that such reflections which cause interference can be avoided.
