The field lens usually works near the focal plane of the objective lens. By adjusting the propagation direction of the light in the optical system, it can correct aberration, adjust the field curvature or control the beam diameter to obtain better optical performance. The application of the field lens is very extensive. For example, in the fields of laser marking, laser cutting and laser engraving, etc., the flat-field focusing lens can form a uniformly sized focused spot on the scanning plane through its special design, so as to achieve high-precision processing. However, the current optical field lens still has the following deficiencies:
