Could you please add a couple of screenshots of your MFE and the Geometric Encircled Energy analysis window (including its settings)? In the screenshots you have shared earlier, the sampling is too low. Once we make sure that all the settings are aligned, we can further investigate the reason behind the discrepancy between the numerical results.&lt;br&gt;&lt;br&gt;Regarding the use of DENC operand, do you compare its value with the Geometric Encircled Energy plot while &ldquo;Multiply by Diffraction Limit&rdquo; is checked? When checking this option, OpticStudio simply approximates the diffraction encircled energy by scaling the geometric data by the theoretical diffraction limit curve computed for a rotationally symmetric Airy disk. However, if your mixed mode system is not rotationally symmetric, you would need to perform an exact diffraction calculation (e.g., the Diffraction Encircled Energy feature).&lt;br&gt;&lt;br&gt;&lt;br&gt;&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-404060","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi Ali,Apologies for the delayed response.The GENC operand and the Geometric Encircled Energy should return the same results since they are using the same computation algorithm.
