Image projecting apparatus
摘要:
An image projecting apparatus includes a light source, a relay lens, a reflective light valve, and a projection lens. The light source is capable of emitting a light beam. The relay lens is disposed to permit the light beam provided by the light source to pass therethrough, and has a lens periphery formed with a notch. The reflective light valve is spaced apart from the relay lens, and is disposed to receive and modulate the light beam passing through the relay lens into an image light beam. The projection lens is disposed proximate to the notch of the relay lens, and is capable of projecting the image light from the reflective light valve to display an image onto a screen. The relay lens has a plurality of light-absorbing regions proximate to the notch for reducing a light-splitting effect attributed to the notch.
