ILLUMINATION OPTICAL DEVICE CAPABLE OF IMPROVING THE ACCURACY OF LIGHT CONCENTRATION ACCORDING TO COLOR LIGHT DURING A PROCESS OF CHANGING A TWO DIMENSIONAL BEAM INTO A ONE DIMENSIONAL LINE BEAM

摘要

PURPOSE: An illumination optical device is provided to simply improve the chromatic aberration by simply transferring the location of a first anamorphic cylinder lens.;CONSTITUTION: A collimator(120) receives the beam which is emitted from a light source(110). The collimator collimates the input beam in parallel. A beam former comprises a first anamorphic cylinder lens(131) and a second anamorphic cylinder lens(132). The beam former diversifies the shape of the input beam in a circular beam. The first anamorphic cylinder lens receives the beam collimated in parallel. The second anamorphic cylinder lens receives the beam passing through the first anamorphic cylinder lens. A line beam generator(141,142,143) generates line beam outputted from the beam former.;COPYRIGHT KIPO 2011
