Be aware that using the RMS spot size from a spot diagram calculation
makes a good operand only when you are close to a good solution
because otherwise it can be a weak operand with respect to many
variables.

I have run a lot of tests when I was building my own program.

It is many times better to target the delta x and y values for each
ray in a spot diagram as is done in CODE V and ZEMAX.

There is a way to do what you want to do but as I don't use OSLO, I
don't know how to do it in that code.

Dear James

Thank you for your answer,
I see that I can't use SPD for optimization operand, maybe you can
avise me,
I've optical system with poltchromatic light sourse. I want to
optimize her for some wavelength (for example 560nm), all other
wavelength in de-focud. So if I put aperture stop in the output I get
max intensity in 560nm wavelength and other with low intensity. I
want use RED to be a parametr to knew how system focused.
My questions is:
1. Is system with best focus has minimal SPD or maximal (most "rapid")
RED? (I see it's don't correlative).
2. Is Oslo has some build in Error function for optimazin to minimal
RED?

I cannot understand your question due to your poor english. Please
try to rephrase. However, using built in merit functions and operands
that try to minimize more than one aberration at a time is nearly
always bad.

If possible, design your own merit function. (Why is it called merit
function when it's really an error function? Very annoying!)
If you have a rotationally symmetrical system this should not be
difficult.
