Assembly Instructions

Housing of focusing optics gets hot!
Touching the focusing optics can lead to serious burns.
Ø
Only use safe combinations of laser device, laser light cable
and focusing optics.
Numerical apertures cannot be combined
If the numerical aperture of the focusing optics is smaller than
the numerical aperture on the decoupling connector, a part of
the laser light hits the aperture of the focusing optics. The hous-
ing of the focusing optics can heat up strongly as a result
(> 300 °C). The following dangers result from this:
■
Fire hazard: Materials in the environment of the focusing
optics can catch fire.
■
Risk of burns: People who work with the focusing optics
may suffer burns.
■
Risks from escape of laser radiation: People in the envi-
ronment of the focusing optics may be injured by escaping
laser radiation. Skin burns and loss of eyesight are possible.
If the numerical aperture of the incoupling connector of the laser
light cable is smaller than the numerical aperture of the laser
device, a part of the laser light is coupled into the connector of
the laser light cable. This results in increased scattered light.
The laser devices switches off automatically.
Wavelength spectrums do not match
Focusing optics are designed for defined wavelength spectrums.
If a focusing optics is operated with a different wavelength than
specified, unforeseen reflections and transmissions to optical
components may occur. The housing of the focusing optics can
heat up strongly as a result (> 300 °C). The following dangers
result from this:
■
Fire hazard: Materials in the environment of the focusing
optics can catch fire.
■
Risk of burns: People who work with the focusing optics
may suffer burns.
■
Risks from escape of laser radiation: People in the envi-
ronment of the focusing optics may be injured by escaping
laser radiation. Skin burns and loss of eyesight are possible.
■
Risks of laser radiation in eyepiece and stereo micro-
scope: People who look into the eyepiece or the stereomi-
croscope during the processing operation can lose their eye-
sight.
