請問誰知道國際光學(xué)圖紙這個標(biāo)注什么意思？
Surface quality: 60-40 X\BdN Hr
f^ [m~
The surface marked R1 is conic surface (aspheric surface) with folowing equation: ZrWA ,~;
Y^2=2 R1_0 X - (1- e^2) X^2 where R1_0 = -10.700B0.010 & e^2 = 0.060B0.003 Qr~yHFc1y

里面的半徑公差給了，但是咱們國家標(biāo)準(zhǔn)一般使用光圈來表示，如何換算呢？ <{. pY rn
