Camera Adapters

The camera adapter allows process observation of the working plane of the galvanometer scanning head by means of a camera. This makes it suitable for process control during laser processing or for inspection of workpiece position and orientation.

Its mechanical interface can be mounted directly between the scanning head and the laser flange. Four camera placement positions are available for setting up the objective unit, ensuring easy integration into existing or new systems.

In order to observe the working plane, the light from there is decoupled in the camera adapter via a beam splitter and imaged onto the sensor via the camera objective. In contrast, laser radiation is transmitted almost unimpeded on its way to the scanning system.

vision for scan heads

The camera adapter enables camera-based observation of a galvanometer scan head’s working field. Typical applications include process monitoring or determination of a workpiece’s orientation during laser processing.

The camera adapter ensures easy integration into new as well as existing systems. The adapter’s mechanical interfaces enable straight forward mounting between the scan head and laser flange. The system allows 4 alternative orientations of the objective with camera.

To facilitate monitoring of www.cniacs.com work surfaces, light arriving from the workpiece is decoupled via the adapter’s beam splitter and directed through the camera’s objective onto its imaging chip. The laser beam on the other hand passes practically unattenuated through the beam splitter to the scan system. Optical configurations are available for various wavelengths. Customers can freely select a camera suitable for their requirements and attach it via a C-mount.

The camera adapter is specifically designed for maximum observation field size and its integrated iris diaphragm can be adjusted for optimal imaging quality. In addition,color or interference filters can be installed.

Layout and Principle of Operation

The solidly designed Collimation Module includes an adapter for mounting the module and scan system to a machine.

Installation 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 movable collimation optic.

This allows precisely setting the focus position to the scan system’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 collimation 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 www.cniacs.com reflected by the beam splitter to establish a 90° angle between fiber-in and beam-out.
