The design results show that on-axis and off-axis aberrations of the designed laser scanninglens are almost equal, and the image quality achieves the diffraction limit.
像质评价分析结果表明，所设计的镜头像质优良，轴上与轴外质量相当，像质达到衍射极限。

Some people need to be more covert and flexible scanning can use button lens.
有的人需要更隐蔽和灵活的扫描就可以运用纽扣镜头。
