Nov 29, 2020 at 9:16 | comment | added | Kphysics | ...contd...And the second question is, if are you going to allow d ~ R in other words a a really thick lens, how well is it going focus? Is this correction to the first formula worth it? | |
Nov 29, 2020 at 9:16 | comment | added | Kphysics | Focal length of the lens is the place where a parallel bunch of rays converge. Spherical lens does not, in fact, collect those rays into one exact location. Thus, it is said that the first well-known formula is valid only for f>>R and of course f>>R>>d even though d does not even enter the first formula. Now, you are asking for a more complicated formula where f is modified by d. The first question I would ask, if this thickness d is not too small, are you going to measure the distance to the focal point from the front or the back of the lens? | |
