The numerical aperture of the laser light cable and the focusing
optics must not be smaller than that of the laser device.
Laser device Optical laser cable Focusing optics
Wavelength = LLK, =focusing optics =laser device, =focusing optics =laser device, = LLK
Rated output ≤ LLK, ≤focusing optics ≥ Laser device ≥ Laser device

Dangers due to impermissible combinations
Laser radiation escaping!
Laser radiation can damage skin and eyes. Damage to
eyesight or even complete blindness can result.
Ø Only use safe combinations of laser device, laser light cable
and focusing optics.
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.
