Section 1: Image formation •L e n s e s are used to focus and manipulate light. In this class we will investigate the science of image formation and discover what sort of surfaces are necessary to form an image. Before taking this class please read through the ‘ Optics Pre requisite Material ’ slides and take the associated ebCT st WebCT test. ©AGK 2010 Geometric optics 1: Lenses and lens combinations 3

Learning outcomes After completing this section you should be able to: Define ‘imaging’, and relate to wavefront behaviour Explain what is meant by stigmatic imaging •D e s c r i b e requirements for ideal lens surface (and relate to Fermat’s principal) •L i s t some common aspheric surfaces ©AGK 2010 Geometric optics 1: Lenses and lens combinations 4

Sample problem • Hecht 5.4 (solution in Hecht): • Diagramatically construct both a sphero elliptic positive ns and an llipto heric egative lens showing rays and lens and an ellipto spheric negative lens, showing rays and wavefronts as they pass through the lens. Do the same for an oval spheric positive lens. ©AGK 2010 Geometric optics 1: Lenses and lens combinations 5
