6.1 Intended use
The focusing optics is intended exclusively for processing work-
pieces made of solid metals or metal alloys.
The focusing optics can be operated within different wavelength
spectrums. The wavelength spectrum, for which the optical ele-
ments of the focusing optics are optimized, is indicated on the
adhesive label attached to the focusing optics.
The wavelength spectrum depends on the laser device to which
the focusing optics are connected.
The focusing optics is set to a reference wavelength.
If the focusing optics is operated with a wavelength other than
the reference wavelength, the focal position will be moved. This
effect is due to dispersion of the lens material.
If the wavelength of the laser device is smaller than the refer-
ence wavelength, the beam cone shortens
If the wavelength of the laser device is larger than the reference
wavelength, the beam cone extends.
Note
A label on the focusing optics indicates for which wavelength
the focusing optics is optimized. A label with the information "λ=
1030 [930-1080]" means, for instance, that the focusing optics is
set to 1030 nm and can also be operated between 930 nm and
1080 nm, but that it then has a different focus position.
