摘要： A projector and the integration rod thereof are disclosed. The integration rod includes an entrance face, an exit face and a side face extending from the rim of the entrance face and reaching the rim of the exit face. The normal line through the geometric center of the entrance face does not coincide with that through the geometric center of the exit face whereby compensating a non-uniformity image resulting from the projector design factors, and therefore improving the uniformity of the image projected on a screen.
