Hi all,

I’m new to Zemax, and I’m struggling on finding the exact distance between surfaces.

I understand that normally the distance between surfaces depends on the thickness that has been set in the lens data editor. However, in the off-axis system I’m designing at current moment, I found that applying Decenter Y will change the distance between surfaces. Now, I’m using the measurement tool to find the distance between surfaces after applying decenter Y. Is there any other method to tell me the accurate distance between surfaces?

Thanks in all in advance.
