10.1 INTRODUCTION
A typical lens is made of glass or plastic. Lenses are classified in two categories: thin lenses and thick lenses. Each category has its applications and equations for calculations. Lenses have two refraction surfaces; each surface is a segment of either a sphere or a plane. Lenses are commonly used to form images by the refraction of light. Light refraction in lenses is one application of the theory of the second law of light: the law of refraction. Lenses are used in building optic/optical fibre devices and instruments, such as cameras, microscopes, slide projectors, and fibre optical switches. The graphical method ...
