Question
A lens that is "optically perfect" is still limited by diffraction effects. Suppose a lens has a diameter of 150mm and a focal length of 600mm.
Part A:
Find the angular width (that is, the angle from the bottom to the top) of the central maximum in the diffraction pattern formed by this lens when illuminated with 540nm light.
= ______________ radians
Part B:
What is the linear width (diameter) of the central maximum at the focal distance of the lens?
