Hi,

When reading lens parameters, I come across entrance pupil size and scan angles. Although, theoretically I know the definition of entrance/exit pupil but I am struggle with its practical application. The same with the field size parameters stated on the tube lens description. I will be grateful for some straight language explanation. 

Regards,

Marzanna
