Hello everyone,
My goal is to reduce the number of diffractive zones on my lens surface, shown below.
Surface Type: Binary2.
I modified the Normalization Radius value. But while optimizing I want to fix the number of diffactive zones.
Any comment or idea on this?
I’ll be appreciated.

The number of zones will be set by the maximum phase excursion. Have a look at the SPHS and DPHS operands to control the phase of the surface.
