Laser Marking Head - High-speed Galvo-scanner With ±25ⰠScanning Field | Precision Laser Deflection, F-theta Lens Integration, Enhanced Marking Software

We are engaged in exporting excellent quality Digital Scanner in Zhuhai, Guangdong, China. A whole laser marking head (or called laser scanner) consists of two scan mirrors, two galvanometers (or calledgalvo-scanner motor)& drive cards (or called driver), a XY mount, a scanning lens (f-theta lens), an interface card (or called D/A card), a set of marking software and a DC power supply.i ?

A laser beam is reflected from two scan mirrors in turn, and directed through a focusing lens. The mirrors are capable of high speed deflection about a rotation axis, being driven by a galvo-scanner motor. In most cases the maximum deflection angle of the mirror is A 12.5A (often A 10A is a safer limit) either side of the non-deflected incidence angle of 45A .

Note that, for best performance, the lens will appear to be a the wrong way rounda when compared with a standard meniscus lens used in conventional focusing of a laser beam.
The laser beam will be scanned over an angleq, equal to twice the mirror deflection angle. So, the typical scanned field might beq=A 20A in both X and Y directions. (q=A 25A would be the usual maximum scanned field). The field size is then approximately 2Ftanq in both X and Y.
