刚才看了一下手册,里面这么写的:
Delete Vignetted If selected, each ray in the merit function will be traced through the system, but if it is vignetted by a surface aperture, if it misses any surface, or if it is total internal reflected at any surface, then the ray is deleted from the merit function. This keeps the total number of rays in the merit function to a minimum. The disadvantage is that if the vignetting changes as the design is optimized, then the merit function may have to be regenerated. It is always a better choice to use the vignetting factors and then use the GQ algorithm than to delete vignetted rays if possible. Vignetting factors can be adjusted, if required, during optimization using SVIG in the merit function.
这貌似就是把渐晕光线删除了,好像也没有对镜片尺寸做操作,也不知道对不对
