zemax中怎么输入一个锥面:
怎么输入锥面?可以在面形调出来呢,还是要编宏?知道赐教一下吧,谢谢
我编过一个Axicon.dll的用户定义面,好久没搞光学了,到时找出来给你,要等一个星期左右
<p>2楼的大哥,能发给我一份吗?</p><p>急需要,谢谢大哥了啊!</p><p><a href="mailto:jiajun.song@accelink.com">jiajun.song@accelink.com</a></p>
<p>如果是圆锥的话可以用奇数非球面来设置,设置它的一次系数即可,系数值是正切值</p>
对,后来我也发现我编的用户定义面是多余的,请按附件做就可以了<br/>
<p>那奇数非球面的前面RADIUS如果取值,而不是∞,将会是什么情况?表示什么意思</p>
<p>用数学知识理解一下就很简单了。每一个面型的公式定义的几何意义。</p>
那天晚上是用一个奇次非球面的,不过非球面系数好像有点限制,有时光线出不来
Zemax manual page 288<br/><br/>Modeling an axicon with the standard surface<br/><br/>The standard surface can be used to make an almost perfect axicon. If (1+k)C^2R^21, the standard surface reduces to <br/> Z=r/sqrt(-1-k) or z=rtan(alpha) , where tan(alpha) = 1/sqrt(-1-k) ,<br/><br/>and alpha is the axicon angle, measured from the XY plane to the axicon surface. To create an axicon, calculate<br/>the conic constant value (k) from the angle (alpha ) desired, and use any small value for the radius of curvature. The<br/>resulting value of k must be negative. The exact value of the radius or curvature is not important, as long as it is<br/>roughly three or more orders of magnitude smaller than the radial aperture of the axicon. The axicon is not perfect<br/>in the sense that there is no cusp at the origin; the region around the surface vertex will be rounded off over a<br/>size given approximately by the radius value. This is actually a desirable property for ray tracing, as the surface<br/>is everywhere smooth.<br/>
