22.12 Diffraction, Fourier transforms and image formation

June 29, 2022July 26, 2022 David HukinsLeave a comment

Before you read this, I suggest you read posts 19.20 and 22.11. In post 22.11, we saw that a microscope forms an intermediate image which is then magnified to give a final image. The picture above uses ray-tracing to show how the intermediate image, A’B’, is formed from the object AB. But I now want… Continue reading 22.12 Diffraction, Fourier transforms and image formation

22.11 The microscope

Before you read this, I suggest that you read posts 22.1, 22.2 and 22.3. The picture shows a microscope. Light passes through a bi-convex lens called the condenser and then through a thin specimen that scatters the light. This scattered light then passes through another lens called the objective. The objective acts in the same… Continue reading 22.11 The microscope
