The Diffraction Limited Spot Size with Perfect Focusing

WebSo this is Fraunhofer diffraction. Here we have to make use of the lens. But why do we use the lens? Because in Fraunhofer diffraction, the source is at infinity so the rays of light which pass through the slit are parallel rays of light. So in order to make these rays parallel to focus on the screen, we, make use of the converging lens. http://prism.mit.edu/xray/documents/Bruker%20GADDS%20Intro%20to%202D%20Diffraction.pdf small basic currency converter
