BFL back focal length xnP!P2  
t^rw@$"}  
ZEMAX defines the back focal length as the distance along the Z axis from the last surface made of glass to the paraxial image plane for the object at infinite conjugates. If no surfaces are made of glass, the back focal length is the distance from surface 1 to the paraxial image plane for the object at infinite conjugates. _P;D.>?  

應(yīng)該就是常說(shuō)的“后焦距”吧

我覺(jué)得也是后焦距

BACK FOCUS 后焦，最后一個(gè)鏡片最后一個(gè)面到相面距離

是后焦距吧 童鞋

翻譯確實(shí)蠻嚇人的。。。唉。。。多謝各位啦！
