Product Introduction

LSSL 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.


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.


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.


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.
