本人新手,因?yàn)槟承┰,需要設(shè)計(jì)工業(yè)相機(jī)鏡頭,初始結(jié)構(gòu)就兩個(gè)透鏡,自己控制了焦距,后焦距,優(yōu)化后三個(gè)波的MTF都沒到極限,本人看了一下賽德爾系數(shù)圖,發(fā)現(xiàn)畸變大,其他的很小,我就想控制畸變,用了dimx, 0狀態(tài)評(píng)估5.6,原先6.4左右。我又想用coma優(yōu)化一下彗差,變化不大,0.4左右,球差評(píng)估0.012 我就沒優(yōu)化,AXCL評(píng)估1.214,LACL評(píng)估-0.106,FCGS ,FCGT 0.051 I"~xDa! i<0D
Z_rub 用以上這些操作數(shù)控制優(yōu)化,發(fā)現(xiàn)MTF優(yōu)化不明顯,光斑rms半徑16 到92微米 7d%A1}Bq$ \;'_|bu3.
