When tolerancing and optical system, it is very important that you analyze and understand the results of the tolerance analysis.  Sometimes, a certain tolerance or Monte Carlo run might produce suspicious results, requiring further in-depth analysis.  The SAVE tolerance control operand and the ability to save Monte Carlo files make this job much easier and give you full access to what ZEMAX has done to the compute the tolerance analysis.
