20090306477 | Optical System - The invention relates to an optical system that is capable of taking images having a wide angle-of-view in simplified construction, is of small-format size and well corrected for aberrations, and has high resolving power. The optical system is an imaging system that is to image an object plane ( | 12-10-2009 |
20090310230 | Transmitting optical element and optical system using the same - The invention relates to a transmitting optical element that is capable of taking images having a wide angle-of-view in general, and an image coming primarily from a vertical direction to a center axis in particular in simplified construction, is of small-format size and well corrected for aberrations, and an optical system using the same. The optical system is an imaging system that is adapted to form an object ( | 12-17-2009 |
20100007969 | OPTICAL SYSTEM - The invention relates to an optical system which is adapted to form an image having a full 360° (panoramic)-direction angle of view on an image plane or project an image located on an image plane in a full 360° (panoramic)-direction angle of view, and which is of small-format size and high resolving power yet without being affected by flare light. The optical system comprises a front unit ( | 01-14-2010 |
20100014174 | WIDE-ANGLE OPTICAL SYSTEM - The invention provides a superwide-angle imaging or projecting optical system provided that, albeit being a wide-angle optical system having an angle of view exceeding 180°, is of small size and reduced F-number and fast, and has improved f-θ performance. The optical system consists only of transmitting surfaces, and has an angle of view of 180° or more. The optical system comprises a front group (G | 01-21-2010 |
20100091393 | OPTICAL APPARATUS - The invention relates to an optical apparatus allowing images in multiple directions to be simultaneously taken with simple construction using a prism optical system yet with high definitions even at wide angles of view. Specifically, the invention provides an optical apparatus using a prism optical system which has three optical surfaces: a first surface having transmission, a second surface having internal reflection plus transmission and a third surface having reflection and is formed of a medium having a refractive index of 1.3 or greater and in which light enters the medium through the first surface, is totally reflected at the second surface, and then reflected at the third surface | 04-15-2010 |
20100238568 | Optical System - The invention relates to an optical system which is adapted to form an image having a full 360° (panoramic)-direction angle of view on an image plane or project an image located on an image plane in a full 360° (panoramic)-direction angle of view, and which is of small-format size and has reduced light flare and high resolving power. The optical system comprises a front unit ( | 09-23-2010 |
20140177043 | Three-Dimensional-Endoscope Optical System - Provided is a three-dimensional-endoscope optical system that is provided with two objective optical systems having optical axes, which are arranged with a spacing therebetween, and that satisfies the following conditions: | 06-26-2014 |
20160070094 | STEREOSCOPIC IMAGING OPTICAL SYSTEM ASSEMBLY, STEREOSCOPIC IMAGING APPARATUS, AND ENDOSCOPE - A stereoscopic imaging optical system assembly including a first optical system at least including, in order from an object side to an image plane side, a negative lens and an aperture, the first optical system being rotationally symmetric with respect to a first center axis, a second optical system that is rotationally symmetric with respect to a second center axis parallel with the first center axis, and that has the same construction as, and is located in parallel with, the first optical system, and a variable optical system located in such a way as to intersect the respective optical paths through the first optical system and the second optical system. The variable optical system effects a change of at least either one of focus and vergence. | 03-10-2016 |
