镜头及线扫检测装置
By using a symmetrical lens group structure in the lens design, the problems of large lens distortion and uneven image quality are solved, achieving a uniform image quality and low distortion imaging effect across a large target area and magnification range.

AI Technical Summary
Existing lenses suffer from significant distortion and uneven image quality across a wide magnification range.
The lens design includes a first lens group with positive optical power and a second lens group with negative optical power, arranged sequentially from the object side to the image side. The first lens group includes a first positive focal lens group, and the second lens group includes a second positive focal lens group. The symmetrical design corrects coma and spherical aberration, while the second lens group corrects off-axis aberration.
It effectively corrects lens distortion, ensures uniform image quality across the magnification range, and supports large target area, large aperture, low distortion, and high relative illumination.
