I wonder if it is possible to analyze the amount of incident energy according to tolerance through Criterion's 'Merit Function' or 'User Script' in the SC rather than the NSC during tolerance analysis. (I want using Monte Carlo Simulation)
Energy is important because the amount of incident light determines the performance of the optical system.
Energy change due to AR coating repeatability is considered separately.
Thank you in advance.

You can use the encircled energy criterion to get the amount of energy on your detector. Be careful that the result will be in afocal units if your system is afocal and Afocal Image Space is ticked in the System Explorer.
For example I have opened the sample file called "Zemax\Samples\Sequential\Afocal\Beam Expander.ZMX".
We can see that 86% of the encircled energy is contained in an angle of 3.7 arcsec around the average.
You can untick afocal image space to get a result in distance.
You can also use the Geometric Image Analysis to do that and use the IMAE operand.
All these operands can be retrieved with a script and during the sensitivity and Monte Carlo run.
I am not sure I understand this last sentence “Or is it only possible to sensitivity analysis according to the tolerance change of a single component after non-sequential conversion using the 'convert to NSC Group' function?” What do you mean there? Sorry.
