;TIR: total internal reflection. A glass or plastic "lens" that collimates light rays from the light emitter, both by reflecting them and by refracting them. Theoretically, ALL of the light produced by the emitter is gathered by the TIR optic. See article [[Lenses]]. | ;<span id="TIR">TIR</span>: total internal reflection.
