The best laser technology available in a small cube

The part coding and laser marking markets have been thriving recently. This upward trend is largely due to the growing demand within numerous industries for product traceability and flexible programmable processes. SEI Laser are in a position to meet this growing demand by launching ‘LASER3’ (laser cube) the latest laser marking system exploiting long life DPSS technology operating within the infrared spectrum (1064nm).

The main feature of this latest SEI Laser solution, besides a peculiar optic frame of laser beam, is the fact that the laser cavity, scan head and full digital electronic control are fitted in a unique small cube measuring just 360 x 260 x 200 mm.

Thanks to the high peak power available (over 130kW ) the LASER3 is ideally suited to removing coatings on both flat and uneven surfaces, marking logos, alphanumeric codes, bi & three-dimensional barcodes (Data-matrix) on materials such as metal, plastics, silicon and PCB surfaces. LASER3 is designed using the latest digital Galvo scan head technology designed by SEI’s in-house R & D lab, featuring extremely high accuracy (TEM00 with M2<1.5 and a spot size lower than 25 microns) coupled with an estimated average laser output of over 20,000 hours (MTBM), the end result is a system unequalled within today’s market. The “on-board” optics can be configured with assorted focal lenses to achieve a maximum marking area of 180 x 180 mm. The system also features an automatic fire spot displacement system (dynamic fire). Another advantage of the system is the high thermal stability, unlike the present air cooled systems currently available LASER3 avails itself of an air-thermo stated cooling system TEC (Thermo-Electric Cooled Technology) providing constant temperature output in the range of 10 to 40 °C.

LASER3 is designed to work even in stand-alone mode (without PC) and mark on-the-fly as part of an existing production line. LASER3 is also equipped with digital I/O’s, serial ports RS 232/485 and can be connected to a LAN 10/100 network. LASER3 is the ideal marking tool easily integrated in production lines and ancillary automatic systems, it meets the growing production demands of both workshops and larger companies, its flexible design enables the system to be configured for both OEM use (class 4 CEI En 60825-1) as well as integrated in a professional laser work center (class 1).
