    How can I determine the properties of a thin lens using basic formulas?

    Thank you so much! I knew I was just missing something obvious! I think I've got parts a, b, c, d, and f correct. But I'm still a bit unsure of what is being asked in part e? I don't know what they mean by format size. Any ideas? Again thank you for your help. a. the effective focal length...

    Help Needed: Calculating Wavefront Error from PV Measurement

    Thank you for the response. I feel the same way that's why I was asking. There is no mention of specific type of aberration in the question, and as far as I can tell from the reading you can use any number between 3-5 depending on the different aberration you are dealing with. I was hoping...
