Information plates about the fiber end position Fig. KR-08142
Position of the fiber end: -4 mm!
If the wrong combination of laser light cable and focusing
optics is used, the destruction of the laser light cable or
the focusing optics may result.
Ø
If there is an information plate "Attention: only for fiber end
position -4" on the plug receptacle of the focusing optics,
the focusing optics may only be operated with a TruFiber
FD34 laser device.
TruFiber FD34 laser devices are characterized by the following
features:
■ "FD34" printed on the nameplate
■ Blue information plate "fiber end position -4 mm" on the LLK
plug
■ This does not apply to laser devices TruFiber FD34-50.
Safe combination of laser device, laser
light cable and focusing optics
