Good afternoon, dear colleagues.
I’m working with optical testing of the convex aspheric mirror. In the interferogram simulation I’ve got stripes like it is shown at the picture. There is a strange white circle at the edge of interference pattern. On the Optical Path figure you can see something like a break of the plot. Is it possible to fix this wavefront break?
I use Binary 2 surface to model diffractive optical element (corrector of spherical aberration). Perhaps, it’s an approximation error of the wavefront, because this surface use polynomials to set a phase shift.
