Dear ZEMAX team,

     I read the KA-01868, and downloaded the attachment file, the infinity-corrected microscope imaging system was straightforward.

     and then I downloaded the according black-box files of the objective and tube lens from Thorlabs website

as you can see, there are differences of black-box thickness and clear semi-diameter between the figure 1 and figure 2,3,  would you please explain this to me?
