1064nm F-theta Lens Laser Marking

Product Description

Monolithic flat field scan lens are designed for laser scanning system, widely used in drilling and marking fields. 

According to the wavelength: 1064nm F-Theta Lens (also called YAG F-Theta Lens), 10.6um F-Theta Lens (also called CO2 F-Theta Lens), 355nm F-Theta Lens (also called ultraviolet F-Theta Lens), 405nm F-Theta Lens, 532nm F-Theta Lens (also called Green Light F-Theta Lens).

1064nm f-theta lens

10600nm f-theta lens

355nm f-theta lens

405nm f-theta lens

532nm f-theta lens

The main functions of the field lens are:

(1) Improve the ability of the edge beam to enter the detector;

(2) In the same main optical system, the additional f-theta  lens will reduce the area of the detector. If you use the same detector area, you can expand the field of view and increase the incident flux;

(3) The modulation disk can be placed at the position of the image surface to solve the problem of nowhere to place the modulator;

(4) Make the non-uniform illumination on the photosensitive surface of the detector uniform;

(5) When using a flat f-theta lens, a flat field image plane can be obtained;

(6) In terms of aberration correction, the curvature of field and distortion of the system can be compensated.
