Fig. 66
CoeLux Quality Control Stamp
Three different cases have been identified according to the type and quantity of ring marks,
impurities and/or particulate matter, which may be found on the surface of the mirrors when
the boxes are opened, each of which will be treated differently.
At least three operators are required to remove the packaging and check the mirrors. During the
check, one of them must take the projector, switch it on and point it at the mirror at a 45
o
angle
of incidence from a distance of at least 1.5 m. The other two operators must analyse the surface
of the mirror for approximately 30 seconds (holding it vertically) and assess the degree of
cleanliness.
WARNING! POSSIBILITY OF BEING DAZZLED
As the light may touch his face, the operator must take care to hide the dazzling light source with his
hand in front of his eyes in the direction of the light. It is possible to find a position, which will enable him
to check the quality of the mirror and not be dazzled at the same time.
