Layout and Principle of Operation

The solidly designed Collimation Module

includes an adapter for mounting the mod

ule and scan system to a machine. Installa

tion is possible from four sides, providing a

high level of integration flexibility.

Various fiber adapters are offered for laser

coupling. The water-cooled, stainless-steel

beam entrance aperture is corrosion-free

even when using DI water. A scale ring

facilitates manual adjustment of the mov

able collimation optic. This allows precisely

setting the focus position to the scan sys

tem’s nominal working distance, as well as

compensating for tolerances.

Housing

The Collimation Module‘s robust housing is

dust and splash proof – particularly at the

junction to the scan head. A replaceable

protective window in front of the collima

tion optic additionally protects the lens

unit from dust infiltration when changing

fibers. This guarantees a long service life in

industrial environments.

Optional Camera Port

The Collimation Module can be optionally

equipped with a camera adapter for process

control or workpiece position detection. The

light arriving from the workpiece is coupled

out of the laser beam path by an integrated

beam splitter and directed to an observation

port. The laser light itself, however, is

nearly fully reflected by the beam splitter to

establish a 90° angle between fiber-in and

beam-out.
