LSSL-SC Series Marking Heads

LSSL SC series laser marking head is an ultra-compact one which delivers excellent dynamics and superior product quality in a minimum-size package. The solid performance of the marking heads is made possible by the new, miniaturized servo amplifiers and industry-proven OSSL series galvanometer optical scanners. Aperture of 7, 10 and 14mm are available.

Sealed against water and dust, the LSSL robust and exceptionally compact housing facilitates straightforward integration into production environments-even confined, difficult to-access locations. A wide variety of objectives can be used with these scan heads.

Versions with analog or digital interfaces are available. The digital version can be simply controlled via a PCI interface board or PC-independent standalone board. LSSL scan heads are ideally suited for solutions requiring very high marking speeds and integration in confined spaces. Applications include coding in the packaging industry or the marking of electronic components – areas traditionally served by inkjet systems.

Optics

We precisely optimize and tune all optical components to one another to ensure maximum focus quality and stable process parameters. Optical components offered by us include exceptionally compact objectives, as well as objective adapters for standard objectives. Optics for various wavelengths, power densities, focal lengths and image fields are available.

Control

LSSL marking heads are equipped with either an analog or a digital standard interface accessible via a 25-pin D-SUB connector. They are easily controlled via PC interface board or the PC-independent standalone board from us.

Quality

The high quality is the result of years of experience in the development and manufacture of galvanometer optical scanners and scan systems. In addition, every scan system must first pass the quality check burn-in test before it is released for shipment to the customer.

LSSL-HS Series Marking Heads

These compact scan heads provide optimal solutions for nearly all challenges found in industrial laser materials processing. The mechanically and electrically inter-compatible scan heads have apertures ranging from 7 to 30 mm and various levels of dynamics. High long-term stability and low drift values are ensured via integrated temperature stabilization.

We have products for practically every customer needs. Small aperture systems optimally combine top speed and exceptional precision. Marking speeds exceeding 1000 characters per second can be achieved.

Also available are large-aperture scan heads offering small spot size, high speed and laser-power handling up to the multi-kilowatt range.

The housing concept as well as tight manufacturing and assembly tolerances bring high flexibility and certainty to the design and operation of laser materials processing systems. This also facilitates speedy adaptation to inpidual customer requirements. In conjunction with new electronics, these scanners deliver highest dynamic performance, lowest drift and best linearity.

Typical Applications:

Optics

Scan mirrors and objectives with optimized mounts are available for all typical laser types and working fields. To optimally utilize standard objectives, LSSL-HS-25’s two scan axes have differing maximum scan angles. This results in an elliptical image field with the larger semi-axis perpendicular to the entrance beam axis.

Control

All scan heads of these series are equipped with either analog or digital standard interfaces and are easily controlled via our control boards. All scan heads are optionally available with an optical fiber data interface.

Attachment Provisions

Threaded and non-threaded holes at the housing’s beam entrance side of LSSL-HS-20, -25 and -30 facilitate mounting of the scan head and installation of fiber optic outputs. On the beam exit side, threaded holes are available for attaching add-on components such as cross jets, illumination, distance sensors or thermal shields.

Cooling

The LSSL-HS-20, -25 and -30 scan heads provide water-cooling connections for the entrance aperture, electronics and galvanometer scanners, along with air-cooling of the deflection mirrors. This ensures constant working conditions and excellent long-term stability, thus guaranteeing reliable operation even in high-laser-power applications.
