oslo优化问题

<P>新手请教：</P>
<P>1.请问oslo中如何控制出射角，即chief  ray angle，需要加入什么操作运算元？</P>
<P>2.GENII函数怎么用，建立函数以后为什么产生不合理的结果，如镜片厚度变为负数。</P>
<P>以上问题希望得到高手或者有经验者指导，或了解者一起讨论，谢谢！</P>

为什么没有人回答，大家都很忙吧，帮个忙吧

add constrain or freeze some thickness.

<P>dfjss : Thank you very much first !</P>
<P>GENII function is the a powerful function .I had do what you said --add the TH constrain in the variables spreadsheet , but it is no use .Why ? please help me .</P>

if th is no use ,you can improve the constrains constant. it is in optimization condition's spread sheet.

if you want control the edge thickness, just use eth(si,sj) constant.

出射角用IANG控制，厚度用ETH和PL控制

Solve for the surface curvature such that the exiting paraxial chief ray has the specified slope.</P>
<P><FONT size=5>pyc </FONT>command
Solve for the surface thickness such that the paraxial chief ray is incident upon the next surface at the specified height.</P>

puc also can solve this problem
