Thankyou

Hi Girish,
Thanks for your question here!
Are you using the afocal system? If you are judging divergence and collimation, the afocal system is recommended. During analysis of these systems, a different reference or different units are usually required. OpticStudio handles this behind the scenes when the user enables Afocal Image Space.
In the afocal system, Spot Radius uses the angle information to determine. So it helps you to determine the divergence and collimation of the system. For a more detailed explanation, please refer to this article https://support.zemax.com/hc/en-us/articles/1500005488001-How-to-design-afocal-systems
Best,
Sean
