  • Projection apparatus having light beam adjusting element
    Patent number: 8721086
    Abstract: A projection apparatus includes an illumination system, a light valve, a light beam adjusting element, and a light reflective unit. The illumination system is capable of providing an illumination beam. The light valve, the light beam adjusting element, and the light reflective unit are disposed on a transmission path of the illumination beam. The light valve is disposed between the illumination system and the light reflective unit. The light valve has an active surface for being capable of converting the illumination beam into an image beam. The light beam adjusting element is disposed on the transmission path of the illumination beam and between the illumination system and the light valve. The light beam adjusting element includes at least one lens having a first optical axis. The first optical axis and a normal vector of the active surface are not perpendicular to each other.
