1064nm F160 110*110mm F Theta Lens For Fiber Laser Marking Machine and YAG Laser
Products Description:
1064nm Fiber / DPSS / YAG Laser F-theta Lens
F-Theta lens, also known as scan lens, is a professional scan lens system, the purpose is to form a average spot of the laser beam in a certain marking field, it is one of the most important accessories of laser marking machine.
The main indicators of the scan lens are scan field and focal length, normally, the scan field is related to the focal length, the longer focal length, the bigger scan field.But as the focal length increases, the diameter of the focused spot also increases correspondingly, which means when the scanning area reaches a certain level, the light spot diameter is large, which means that the marking spot is not fine enough, the power density decreases very fast.
YAG scan lenses are widely used in YAG laser marking and drilling machine. The lens is also applicable with fiber laser machines.
YAG scan lens is used in conjunction with XY galvanometer mirror and beam expander to form a two directions scanning system.
The AR coating is coated on the lens surface to ensure minimal power loss. The scan lens is designed with the industrial standard M85x1 screw thread. So the scan lens is more applicable for all the machines
