Question 5 A simple representation of an electron microscope consists of an electron source (which you can treat as a point source), a condenser lens, an objective lens and an objective aperture. The microscope operates at 200 kV and the objective aperture subtends a semi-angle of 10 mrad with respect to the sample. You can assume that the spherical aberration coefficient, Cs ~ f where f is the focal length of the objective lens. You can ignore chromatic aberration. If the condenser lens is positioned 3 cm from the electron source. What focal length should the condenser lens have to give a parallel beam of illumination on the sample which is located 10 cm from the condenser. Illustrate your answer with a simple ray diagram. (2) An objective lens with a focal length of 0.5 mm is located 0.55 mm after the sample. What is the magnification of the image. (2) In what plane will the diffraction pattern be formed and how far will it be from the sample? (2) Estimate the resolution of the microscope. (6)
