Hello everyone,

In the full-field aberration map, the sampling value of the field of view has a maximum value of 20. When I want to find the minimum point of an aberration, I often cannot get it precisely because of the lack of precision.

I've read the question and the response below, and I am confused that if we use the ZERN operand to read the zernike coefficient value, then a lot of fields need to be setby using zosapi to calculate in matlab. After trying, I found that the fields  can only be set around 2000 at most, and the speed is slow. 

So I want to know how to get the aberration of any field point, and if  there exsits an interface like this, the optimization can be done to find the exact position of the minimum value.
