Quick Detail:

YAG laser f-theta lens can be used for laser marking and laser engraving, work with marking head

(laser scanner).

1064nm F_Theta Scan Lens used in Galvanometer scanning Nd:YAG,Green,and UV laser scanning 

system, It is widely used in Marking and Drilling field.

The marking area should be 112*112or 174*174 or 70*70or 140*140 or 205*205 or 220*220 or

 300*300.

Description:

F-Theta Scan Lens --- Nd:YAG

In most of the cutting edge laser machinery, laser optics will be incorporated into system to realize various applications like marking, drilling, welding, dicing, scribing, cutting, engraving etc. F-theta scan lens is used in conjunction with XY galvanometer scanner and beam expander to form a two dimensions scanning system. The scan lens is optimized to provide a flat field image with diffraction-limited spot size in micron scale over the entire scan field. The image field height is almost directly proportional to the scan angle. Typically, the linearity f-theta distortion is kept less than 1% without software correction to ensure minimal distortion. High transmissive AR coating is coated onto the lens elements surface to ensure minimal power loss and hence increase the throughput.

F-theta scan lenses play a major role in today’s leading-edge laser applications.  Scan lenses for YAG laser systems that are used for marking, engraving, via hole drilling, and more.
