Diffraction from a single slit, with Lens

[QUOTE="Simon Bridge, post: 4538670, member: 367532"] @elette: Welcome to PF; In this problem the slit is right on the lens and the screen is in the focal plane - so L=f ... fine. Thinking of the derivation of the fringe-spacing equation is important - however:... $$\Delta y = \frac{\lambda f}{a}$$ ... does not appear to account for the refraction of the light through the lens. Does the lens have no effect at all? [/QUOTE]
