是实测，不是计算出来的吧？个人看法，不太确定

<p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><span lang="EN-US" style="mso-fareast-language: ZH-CN; mso-fareast-font-family: SimSun;"><font face="Times New Roman">Zemax</font></span><span lang="ZH-CN" style="FONT-FAMILY: SimSun; mso-ascii-font-family: Times New Roman; mso-hansi-font-family: Times New Roman; mso-fareast-language: ZH-CN;">中，玻璃的种类若使用「</span><span lang="EN-US" style="mso-fareast-language: ZH-CN; mso-fareast-font-family: SimSun;"><font face="Times New Roman">model</font></span><span lang="ZH-CN" style="FONT-FAMILY: SimSun; mso-ascii-font-family: Times New Roman; mso-hansi-font-family: Times New Roman; mso-fareast-language: ZH-CN;">」时，可输入「</span><span lang="EN-US" style="mso-fareast-language: ZH-CN; mso-fareast-font-family: SimSun;"><font face="Times New Roman">nd</font></span><span lang="ZH-CN" style="FONT-FAMILY: SimSun; mso-ascii-font-family: Times New Roman; mso-hansi-font-family: Times New Roman; mso-fareast-language: ZH-CN;">」与「ν</span><span lang="EN-US" style="mso-fareast-language: ZH-CN; mso-fareast-font-family: SimSun;"><font face="Times New Roman">d</font></span><span lang="ZH-CN" style="FONT-FAMILY: SimSun; mso-ascii-font-family: Times New Roman; mso-hansi-font-family: Times New Roman; mso-fareast-language: ZH-CN;">」即可喔。</span></p>

如楼上所说，我的问题已经解决了，呵呵

对于玻璃的编号，怎么才能从六位的编号中看出其他的东西？有的人说只要知道了这个6位数，就可以设计透镜了？为什么？

<p>vd=nf-nc/nd-1 想直接算不出来的。先确定是什么玻璃牌号，在ZEMAX会直接算出F光的折射率，不知有没说明白。</p>

Zemax中，只要输入nd与νd，nF可以被计算出来，不需要知道玻璃的名称喔！

呵呵，直到名称，nd都可以自己出来吧：）
