What are the s- and p-polarization states? How do I make my incoming beam s-polarized?  

I am trying to save my Non-Sequential system as an archived file (ZAR) but the file is very large. I know that the ZAR file type is a compilation of several different files that help define the lens file but can I safely remove certain files to reduce the overall file size?

I want to use Importance Sampling to trace scattered rays, but when I do, no rays are traced. How do I fix this without changing my optical design?

I am currently working on a Professional edition of OpticStudio and wish to import a Zemax Part Designer file (.ZPO) into my optical design. However, I am finding that the option to import an object of type “CAD: Zemax Part Designer” is only available in the Premium edition of OpticStudio. Can I import my .ZPO file or do I have to work on a Premium edition of OpticStudio?

What are the benefits of Express View? What are its limitations?

How can I model an elliptical beam in a sequential system?

Does OpticStudio have a preferred compiler that I need to use in order to create my own source?

When I open an archived (.ZAR) file, I get a pop-up referencing existing files. Which option should I choose? Do I always have to overwrite files with the same name, or can I merge them?

I’m building a system in Non-Sequential Mode but keep getting “Geometry error” on the screen when I include layout rays. How do I fix this?

I am working with a system that has a user-defined DLL surface and want to obtain the settings. The ZOS-API recognizes that I am using a user-defined DLL but is not returning the correct file as defined in my code.

Is there a way to model and analyze a system using physical optics calculations instead of a ray trace?

I'm trying to optimize a system with a partner but our results keep coming back different from one another even though we are using the same operands and variables. Why is this happening?
