  • Optical projection system and projector including the same

    Abstract: A light modulation device side lens group has different powers in the longitudinal direction and the lateral direction of a liquid crystal panel. Therefore, as the entire system of the optical projection system, the light modulation device side lens group has different magnification in the longitudinal and lateral directions. Therefore, it is possible to make the aspect ratio of an image of the liquid crystal panel different from the aspect ratio of an image projected on a screen. That is, conversion can be performed on an aspect ratio. At this time, a distance p between each focus or a diaphragm and the screen SC side end surface of the light modulation device side lens group satisfies the conditional expressions, so it is possible to achieve a predetermined or higher telecentricity in both states, that is, a first operating state and a second operating state.

  • Telescopic gun sight with linear optical adjustment mechanism
    Patent number: 8749887
    Abstract: Telescopic sights commonly include a reticle which is laterally moved to adjust for the point of aim. In this invention, a prismatic device is used to move the image of the target on the reticle. In one embodiment, a pair of prisms are placed in the optical path of a telescopic sight such that at least one prism is movable along the optical axis. The point of aim is adjusted by adjusting the distance between the two prisms. By replacing the lateral movement of the reticle with the longitudinal movement of a prism, this invention eliminates several drawbacks associated with the prior art including limitations in the adjustment range.
