1、多重结构光学系统图

以code.v自带的变焦镜头为例（res cv_lens:movie）

如图示，三重结构焦距分别为：9mm、20mm、36mm；按照下列步骤操作可实现在一张图中显示多重结构。

具体代码：

VIE ! enter the VIEW option
RET Y Y N ! used to overlay zoom positions
OFS Z1 0 2.1 ! offset zoom 1 up by 2.1 inches
OFS Z3 0 -2.1 ! offset zoom 3 down by 2.1 inches
SF 1 ! scale factor (full scale)
NBR SUR S6 GRE ! number surface 6 (in green)
NBR SUR S11 GRE ! number surface 11
NBR SUR S13 GRE ! number surface 13
NBR SUR SI-1 GRE ! number the PIM surface
NBR SUR SI GRE ! number the image surface
RFR N ! don't draw the reference rays
RSI F1 0 1 ! draw on-axis upper marginal ray
RSI F3 0 0 ! draw full field chief ray
LNS S7..10 BLU ! draw first moving group in blue
LNS S12..13 RED ! draw second moving group in red
GO ! execute the option
           

另一种多重结构显示方式：

!Colors for zoom positions
CLS ZOO RED GRE BLU
VIEW
!Put 3 zooms on 1 pg
RET Y Y N
!Overlay zooms at S1
OFS OVE S1
!Scale factor =2
SF 2
!Don’t draw ref. rays
RFR N
!Draw surfs 1 to 6 and
LNS S1..6 BLA
!14 to image in black
LNS S14..I BLA
GO
