PROJECTION APPARATUS

摘要

The projector includes two lamps for object lighting (11) and projection lighting (22). The light from the lamp (11) penetrates an object (16) and focuses the image on a liquid crystal light bulb (21) through an object lens (20) with m???? magnifications. The light from the lamp (22) throws the image on a screen (26) through a projection lens (24) with n magnifications. Then the image of the object is projected with m x n magnifications. The projector also includes a selective mirror (13) selecting the light pathway of the lamp (11) and a full reflection mirror (17) adjusting the light pathway of a light collection lens (12).
