<b><FONT size=4>April 27, 2004</FONT></b> <P><B>New Features</B> <OL type=1><LI>ZPL keyword RANDOMIZE added to control the seed on the random number generator. <LI>ZPL keyword SETDETECTOR added to set values of detector pixels. <LI>New Biconic Zernike surface added. <LI>The Glass Melt Fit feature has a new option to fit the dispersion data only over the wavelength range defined by the melt data points. This greatly improves the accuracy of the fit at the defined wavelengths. <LI>The automatic semi-diameter calculation is much faster for many common non-axial cases, significantly speeding up optimization for these cases. </LI></OL><P><B>Bug Fixes</B> <OL type=1><LI>The Chromatic Focal Shift Plot was computing the shift in air, even if there is glass up to the image surface. <LI>The optimization operand TOLR was causing unused 0 byte sized files to be created in the \TEMP directory. <LI>A bug in the key driver which could cause a "blue screen of death" has been fixed. </LI></OL><P>第一个更新对于编程（ZPL）是很有用的</P><P>第二个：也很有用，对于杂光分析的编程</P><P>第三个：增加了一种面型，当然是一个比较大的更新了，增加了设计的自由度</P><P>第四个和第五个，相当于完善和优化。</P><P>可惜了，我们单位不批钱给我更新了</P>
, 好东西啊！
