Optical Lenses and Devices

  • Jay Newman
Chapter

In the last chapter we learned the fundamental laws that tell us how light behaves when traveling through a transparent material. Here we apply those to the most important case of optical lenses, both human-made, for use in optical devices, and naturally occurring, as in the eye. After learning the basics of imaging using a single simple lens, we show how the human eye exquisitely functions to allow us to see in color at extremely high resolution. Two human-made optical devices, the magnifying glass and the compound microscope, are then examined. These can be fairly well understood with only the tools of geometric optics that we have learned. Understanding the huge arsenal of new optical microscopies studied in Chapter 23 requires knowledge of wave optics, presented in the next chapter. There we introduce the wave nature of light and some of its major consequences.
