A reflective collimator (11) adjusts an input light beam (10) producing an output light beam (30) parallel to the input light beam (10). The input light beam (10) is reflected and focused by a first reflector (16) to a second reflector (20), then reflected from the second reflector (20) to a third reflector (24), and reflected from the third reflector (24) to a fourth reflector (28), and finally reflected and focused from the fourth reflector (28) to a focus point. |
