Hello,

I have a question about Zernike coefficients.

When working with Zernike Standard Phase surfaces, the Zernike coefficients given by Zemax are wavefront error, is this true? In that case, we know the formula:

Wavefront error = absolute error - wavefront contribution of the reference field (reference sphere)

Is is possible to obtain the reference sphere from Zemax, and by substituting in the equation, obtain the absolute wavefront? Is there a way to obtain the absolute wavefront from Zemax?

In my case, I have the absolute wavefront from one surface and I want to transfer it to Zemax to simulate the same surface, do you think it would be possible? Which steps do I need to follow?

Thank you very much,

Alicia
