phase shift thru a thins lens

Ok ihve got the previous one ...

Can u help me out in calculating the Phase Shift through a thin lens of focal length f.

where d is the  lens diameter. and h is the distance from the optical axis.

solution is like this.

P(h) = K/2f [ (d/2)² - h²].

Re: phase shift thru a thins lens

Are you required to come up with your initial differential equation, or is that given to you?
