Much like the SAVE tolerance control operand (which is useful for evaluating one tolerance at a time), you may also save each individual Monte Carlo file generated during the tolerance analysis.  This option exists in the Tolerancing dialog.  In the top-most portion of the dialog, you may choose to specify how many Monte Carlo runs to perform as well as how many of these Monte Carlo files you would like to save for viewing after the analysis is complete.



The benefits to saving the Monte Carlo files are the same to that of the SAVE tolerance control operand.  However, the Monte Carlo analysis simulates the effect of all perturbations simultaneously.  Thus, the saved files will contain the modified Lens Data Editor with possibly many changes/additions (depending upon the number of tolerance operands you have for your system).

Saved Monte Carlo files are also saved to the directory of the nominal lens file and any number of Monte Carlo files may be saved.  The lens files are named MC_T000x.zmx, where x is the value 1 through the maximum number of specified Monte Carlo files to be saved.



In most cases, it isn’t necessary or desirable to review each individual saved Monte Carlo file.  You may use the Monte Carlo Analysis output to help pick out any specific trial that you would like to later review in ZEMAX format:
