从网站(http://www.optotek.com.cn/knowledge-item-129-ZEMAX-Depth-of-Field-ZPL.html)上下载了景深的宏计算文件,如下所示:
! DepthOfField
! Calculate depth of field

FORMAT 8.3
INPUT "Focal length(mm)",effl
INPUT "F/#",fno
INPUT "Subject distance(m)(Input 0 for infinity)",distance
INPUT "Circle of confusion(mm)",CoC
distance = distance * 1000
! 0.00029 is limited resolution angle of human eye in radian
! elsa = 0.00029
enpd = effl / fno
mag = effl / distance
!delta1 = ( distance*distance * elsa ) / (effl/fno - distance*elsa)
!delta2 = ( distance*distance * elsa ) / (effl/fno + distance*elsa)
distance1 = mag*enpd*distance/(enpd*mag - CoC)
distance2 = mag*enpd*distance/(enpd*mag + CoC)
! distance == 0 means focus at infinity
IF distance == 0
distance2 = enpd / (CoC/effl)
distance1 = 0
ENDIF
PRINT ""
PRINT "Calculates Depth of Field..."
PRINT "Focal Length = ",effl," mm"
PRINT "F/# = ",fno
PRINT "Subject distance = ",distance/1000," m"
PRINT "Circle of confusion(mm)",CoC
PRINT "Depth of field in front of subject(m) : ",(distance-distance2)/1000
PRINT "Depth of field behind subject(m) : ",(distance1 - distance )/1000

哪位大神给翻译一下?谢谢!
另外,这些参数在zemax里面怎么找到?求详细教程。
