WIDE-ANGLE IMAGING LENS AND LOW-PROFILE PROJECTION LIGHT ENGINE USING THE SAME
摘要:
Wide-angle imaging lens arrangements and methods are described for use with an image projector system including a display. A plurality of no more than six lenses can be arranged to receive an object image that emits from the display to propagate through the plurality of lenses to produce a high-quality projected image on a screen. The image projector system has a low f-number, low height profile and high resolution.
