Increase the magnification and sharpness of the image in optical instruments
Many
optical instruments consist of a number of lenses. They are combined to
increase the magnification and sharpness of the image. The net power
(P) of the lenses placed in contact is given by the algebraic sum of the
individual powers P1, P2, P3,... as P = P1+P2+P3.
