ABSTRACT
This chapter presents an experiment involving the operation, image formation, functionality, disassembly, and reassembly of the optical components of an optical viewing instrument. There is a wide variety of optical devices, instruments, and systems that use mirrors and lenses, for example: cameras, microscopes, projectors, and telescopes. There are also optical instruments that use prisms, gratings, and fibre optics, along with one type of lens or mirror. Cameras are among the most common of optical instruments. The eye of living creatures is one of the most familiar optical instruments. The optical behaviour of the eye is similar to the optical principle of a simple camera. Many optical devices are used to produce magnified images of objects. The optical instrument known as the telescope applies the principles of lenses and mirrors. Optical components, such as mirrors, lenses, and prisms, work on the basis of image formation by reflection and refraction. These optical components are used in building different optical viewing instruments.
