Section 1.2.2: Image Projection Light source Field Lens Target Objective Lens Projection Lens Condenser Lens Screen I. Place the projection lens behind the objective lens so that an image of the sample target is visible from an arbitrary distance (use the lens equation for thin lenses to calculate its position before implementation). The focal length of the projection lens is 75mm. A. Draw a ray-optics diagram of the entire setup, explain why the image is sharp at any screen distance. B. Calculate the magnification of the final image on the screen. C. What are some properties of the focal point after the condenser. Why is this called the Fourier plane (take a picture)? D. What will happen when the image is altered in this plane, for example, by placing a small aperture or slit (take a picture)? E. What effect does the lens/aperture diameter have in general?
