			<description><![CDATA[This article explains how to use the TOLR operand to perform an optimization that fully accounts for all manufacturing defects. The technique is robust and stable, and takes full advantage of ZEMAX' ability to run large calculations over multiple processors.<br/><br/><a href="http://www.leadin.co.jp/company%20page/zemax/knowledge%20base/how%20to%20Optimization/how%20to%20optimize.html" target="_blank">This article is also available in Japanese.</a>]]></description>

			<link>http://www.zemax.com/kb/articles/121/1/How-to-Tolerance-for-Tilts-and-Decenters-of-a-Double-Pass-System/Page1.html</link>
			<description><![CDATA[This article explains: 
<ul>
<li>How to setup a double pass system for the purposes of tolerancing the&nbsp;tilts/decenters of elements. 
</li><li>How to setup the Tolerance Data Editor with the user-defined operands (TU**) required for accurately modeling lens tilts and decenters in double pass. 
</li><li>How to verify that the double pass system has been adequately modeled to reflect reality.</li></ul>]]></description>

			<description><![CDATA[Many times it is useful to analyze your tolerances in detail.&nbsp; In ZEMAX's tolerance analysis, you may save the tolerance results for each Monte Carlo file, or you may save each tolerance in the sensitivity analysis indidvidually in ZEMAX file format.&nbsp; This article describes how to take a closer look at what ZEMAX does internally to model each and every tolerance in your design.]]></description>
