| 20120019904 | FILTER FOR LIGHT RECEIVING ELEMENT, AND LIGHT RECEIVING DEVICE - Disclosed is a filter for a light receiving element, which can sufficiently eliminate disturbance due to sunlight and the like out of doors. A filter for a light receiving element according to one embodiment of the present invention is used for a light receiving element which receives signal light having a known spectral distribution. The filter for a light receiving element according to one embodiment of the present invention is configured so that when the energy density of the ambient light in the light receiving element is represented by N | 01-26-2012 |
| 20110157898 | ILLUMINATING DEVICE - An illuminating device includes a light source ( | 06-30-2011 |
| 20110002042 | LINE GENERATOR - A line generator according to the present invention includes a light source, a first lens group, and a second lens group. An optical axis is set to a position of a light beam which travels orthogonal to incidence surfaces of both the first and second lens groups and the first lens group is configured such that light beams from the light source are not collimated in a first direction in a plane orthogonal to the optical axis and are collimated or focused only in a second direction orthogonal to the first direction in the plane orthogonal to the optical axis and the second lens group is configured such that the light beams which have passed through the first group form a line. | 01-06-2011 |
| 20100271691 | IMAGING OPTICAL SYSTEM AND RANGE FINDER - An imaging optical system includes three reflecting mirrors having first to third reflection surfaces and is configured, such that in an XYZ orthogonal coordinate system using an optical axis at the center of the field of view as Z-axis, the optical axis at the center of the field of view and an optical axis of an image plane are in parallel to each other by changing orientation of the optical axis in a YZ section while maintaining the orientation of the optical axis in an XZ section. At least one of the three reflection surfaces is rotationally asymmetric. Assuming that along the path of the beam traveling along the optical axis at the center of the field of view a distance between the second reflection surface and the third reflection surface is L | 10-28-2010 |
| 20100172024 | IMAGE FORMING OPTICAL SYSTEM - To provide a compact image forming optical system in which an incident angle to an imaging plane of a solid-state imaging device is small and whose chromatic aberration, astigmatism, field curvature, and distortion are reduced. An image forming optical system of a first embodiment of the present invention comprises four lenses arranged from the object side to the imaging plane side in order, that are a first lens that is a double-convex lens, a second lens that is a double-concave lens, a third lens that is a positive meniscus lens that is convex toward an image side, and a fourth lens that is a negative meniscus lens that is convex toward an object side. An aperture is placed closer to the object than the image side surface of the first lens. The image forming optical system of the first embodiment of the present invention satisfies the following equations, where f | 07-08-2010 |
| 20090127478 | Infrared Source and Method of Manufacturing the Same - There is provided an infrared light source that has a simple structure and radiates infrared rays polarized in a specific direction and having a specific wavelength. The infrared light source ( | 05-21-2009 |
| 20090034079 | Fine grating and mold therefore - This invention provides a mold with which a two-dimensional subwavelength grating can be produced with a higher percentage transfer by injection molding and a two-dimensional subwavelength grating having a high aspect ratio produced with such a mold. The mold for a fine grating according to the present invention has protrusion parts ( | 02-05-2009 |
