Polaroid sunglasses are familiar to most of us. They have a special ability to cut the glare of light reflected from water or glass (see Figure 1).

Depth of field refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print ...

Ray optical

In the last article on the optical invariant, we showed that an invariant exists between any two paraxial rays traced through an optical system (as long as the rays emanate from different object points). We also showed ways the invariant can be used to quickly establish an optical system concept, and ensure that nothing impossible was being attempted. In this article, we will show how the optical invariant, when combined with an optical system's paraxial raytrace, can conveniently lead to detailed first order analyses. As before, we will use an example to illustrate the methodology involved.
