Geometrical Optics

At the end of OPT 215 (Geometrical Optics) course, students should be able to: 1. appreciate the importance of the relationship of optics to the eye’s optical media, particularly the crystalline lens; 2. have good knowledge of the different types of lenses and mirrors; 3. describe the formation of images by both concave and convex mirrors; 4. desribe the formation of images by both concave and convex lenses; 5. describe the principles of reflection and refraction in the formation of images; 6. describe how to use light source to construct images formed through rays tracing; and 7. have knowledge. about some optical instruments and their functions such as telescope and microscope.

The course deals with the study of the nature, properties and phenomena of light in optical media. Principles of geometrical optics including reflections and refractions. Formation of images. The influence of mirrors and lenses. Spherical and cylindrical lenses; mirrors; thin and thick lenses. Lens systems; Ray tracing. Apertures; Prisms. Aberrations. Lens formulae, symbols, design and optical instruments. Neutrallsation; Transposition and specification of ophthalmic lenses. Laboratory work is included.
