POP Arbitrary Input Beam

Dear Sir or Madam,

I have a distorted wavefront from a physical beam I am using in the lab. I would like to use this measured beam profile (see below) and simulate what kind of aberrations this leads to in my downstream optics. Is this kind of simulation possible with Zemax Physical Optics Propagation tool?

Thank you,

Hi George,

Yes, you can perform this type of analysis with POP. You can enter your own input beam properties by selecting File as the Beam Definition:



The File you select is a ZBF type. The definition of a ZBF file is provided in the Help System file 'The Analyze Tab (sequential ui mode) > Laser and Fibers Group > About Physical Optics Propagation > Defining the Initial Beam > File (defining the initial beam).'
