| 8186837 | Wide angle display device A wide angle viewing apparatus for security applications is disclosed. The apparatus comprises a wide-angle lens and a diffusing screen. The wide-angle lens incorporates an image inverter and a means for eliminating stray light. ... | 05/29/2012 |
| 7699477 | Alignment method, alignment apparatus, and alignment screen for objective-lens guiding device An end face of a narrow-diameter end portion is easily disposed at a correct position on an examination object without setting an examination site, thus enabling rapid and straightforward acquisition of an image of the examination site. The invention provides an ali... | 04/20/2010 |
| 7355790 | Optical sight having a reticle illuminated through a non-lambertian light diffuser An optical sight includes an optical train having an optical path therethrough. The optical train typically includes an objective, a prism that receives the optical path from the objective, and an eyepiece that receives the optical path from the prism. A reticle is ... | 04/08/2008 |
| 7245311 | Image forming apparatus A photosensitive body has a photosensitive layer. An optical scanning device has a deflector deflecting a light flux emitted from a light source, and scans the surface of the photosensitive body by the thus-deflected light flux. A dot is formed at a center between a... | 07/17/2007 |
| 7236310 | Device for equalizing the back foci of objective and camera A device for adjusting the back foci of an objective and a camera to one another has a housing by which a graphic pattern and an optics are mounted at a predetermined distance F′ from each other. The temperature compensation for the distance F′ is constant to ±... | 06/26/2007 |
| 7154551 | Imaging device with solid optical member An imaging device includes a convex mirror for reflecting first incident light representing an object, the convex mirror having a shape of solid of revolution; an imaging mechanism for taking a reflected image represented by light reflected in the convex mirror; and... | 12/26/2006 |
| 4957357 | Multiple axis reticle A reticle (10) permits the alignment of three orthogonal axes (X, Y and Z) that intersect at a common target point (30). Thin, straight filaments (12, 14 and 16) are supported on a frame (20). The filaments are each contained in a different orthogonal pl... | 09/18/1990 |
