The performance and quality of a marking mainly depends on the output power and the laser beam focus. cab FL+ marking lasers are diode-pumped and air-cooled. They have high beam quality and pulse peak power. Laser source output powers are from 20 to 50 Watt. Different plano-spherical lenses allow marking in fields from 69 x 69 to 290 x 290 mm. Marking is possible on plastics and metals as well as on coated surfaces. FL+ marking lasers consist of two units. The control unit has a laser source already integrated. The scan head is connected to the laser source via a fibre. It may be assembled in all possible position.
