Tracepro by Lambda Research Corporation: Breaking TIR, is it against the law?

TIR stands for Total Internal Reflection. TIR is the guiding principle of fiber optics, light guides, and light pipes. Total internal reflection means that light rays that meet certain conditions are reflected inside of a light guide with no loss in flux or power. This is great when transmitting light from one point to another where little or no loss is important. There are other cases though, such as displays and indicators, where it is desirable to get the light out of the light guide at some user defined position. This is where breaking TIR is appropriate.
