I am now two weeks before finals!! I am working on previous exam papers and
wonder if you would mind looking at a question for me?
It is "A meniscus lens of back vertex power +12.00D has a nominal
magnification of 2.75 times. The axial thickness of the lens is 9mm and the
refractive index 1.50. Calculate the surface powers of the lens.".
Can you possibly help? It is probably fairly obvious how to do it and I
just can't see it; I think it is to do with the difference between nominal
and surface powers. However without having one surface power I am having
problems. If you can shed any light on it I'd be most grateful at this
stressful time!
thanks in advance, Scott
