Section 1: Image formation • Lenses are used to focus and manipulate light. In this class ill i i h i f i f i d 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 WebCT test WebCT test. ©AGK 2010 Geometric optics 1: Lenses and lens combinations 3

Learning outcomes After completing this section you should be able to: D fi ‘i i d l t t f t b h i Define ‘imaging’, and relate to wavefront behaviour Explain what is meant by stigmatic imaging Describe requirements for ideal lens surface (and relate to Fermat’s principal) List 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 lens and an ellipto spheric negative lens showing rays and 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
