Principal planes method For the purposes of finding images, we can reduce any* optical system to a thin lens. Principal plane distances p 1 and p 2 are.
How Does a Lens Work? Light travels slower in the lens material than in the air around it. This means a linear light wave will be bent by the lens due.

A More General View of Focusing

Reading Quiz A complex imaging system can be reduced to an equivalent: thin lens thick lens thin plate thick plate

Reading Quiz The effective beginning and end of the equivalent thin lens are called the ______ planes dominant primary principal secondary serving

Principal Planes

Reading Quiz For a laser cavity to be stable, the rays must get back to the same height after one round trip must get back to the same height after an infinite number of round trips must remain at a finite height after an infinite number of round trips

Result: should be stable if 1/2 (A + D) is between 1 and -1 Laser Cavities Result: should be stable if 1/2 (A + D) is between 1 and -1

Result: should be stable if Laser Cavities HW P9.15 Result: should be stable if
