20160103294 | OPTICAL DEVICE - Provided is an optical device including an object-side body portion to and from which an eyepiece-side support member supporting an eyepiece system optical component can be attached and removed; an objective system optical component supported on the object-side body portion; a housing section that houses at least a portion of the eyepiece-side support member; a manipulation member by which a rotation manipulation is performed on the housing section; a following member that is driven and displaced by the manipulation member being rotated; and a gripping member that has at least a portion thereof arranged inside the housing section and grips the eyepiece-side support member when the following member is displaced. The manipulation member rotates freely relative to the following member when a gripping force exerted on the eyepiece-side support member by the gripping member reaches a prescribed value. | 04-14-2016 |
20150362588 | DISTANCE MEASURING APPARATUS AND METHOD FOR CALIBRATION - A distance measuring apparatus includes: a light-transmitting unit that transmits signal light from a light source toward a target object; a light-receiving unit that has a light-receiving element and receives the signal light from the target object on an optical axis different from that of the light-transmitting unit; a distance measuring unit that measures a distance to the target object based on propagation time from light transmission to light reception of the signal light; and a compensating unit that, while either optical path of an optical path from the light-transmitting unit to the light-receiving unit or an optical path from the target object to the light-receiving element is fixed, compensates an optical path of the signal light by displacing the other optical path at the light-transmitting unit or the light-receiving unit. | 12-17-2015 |
20150070759 | BINOCULARS - Binoculars including: a pair of lens barrels each having a telescopic optical system; and interconnecting portions interconnecting the pair of lens barrels so as to be relatively rotatable about an axis of an axial member that is parallel to an optical axis of each of the telescopic optical systems, an interpupillary distance being adjusted by relatively rotating the pair of lens barrels about the axial member, the binoculars being characterized in further including: a click position setting mechanism serving to set a click position at a predetermined angle of rotation of the pair of lens barrels, the click position setting mechanism being configured to include a rotating member provided on the axial member so as to rotatable about the axis of the axial member and facing the interconnecting portion in a direction of the axis of the axial member, a protruded portion being provided on any one of the interconnecting portion and the rotating member, and a recessed portion being provided on the other of the interconnecting portion and the rotating member and being capable of engaging with the protruded portion; and a lock/unlock member locking the rotation of the rotating member with respect to the axial member and unlocking the locked rotation thereof. | 03-12-2015 |

20130010278 | DISTANCE MEASURING APPARATUS - The present application provides a distance measuring apparatus that can measure a distance with accuracy even when a light receiving level of a reflected light becomes saturated. A light emitting section of the distance measuring apparatus emits a measuring light toward an object to be measured. A light receiving section receives the reflected light being reflected from the object to be measured. A distance calculating section obtains a distance to the object to be measured based on an elapsed time which is from a point the measuring light is emitted until a point a light receiving level of the reflected light indicates a peak thereof. A distance correcting section corrects a value of the distance to the object to be measured depending on a length of saturation time of the light receiving level when the light receiving level becomes saturated and the peak is impossible to identify. | 01-10-2013 |
20120113409 | RANGE FINDER - A laser range finder includes: a light source emitting light from a linear light-emitting portion with making a divergent angle of the light larger in a transversal direction of the light-emitting portion than in a longitudinal direction thereof; an objective lens projecting the light onto a target object and converging reflection light; a partial reflection member disposed between the light source and the objective lens and having a partial reflection surface composed of a transmitting area transmitting light emitted from the light source and receiving areas reflecting reflection light; and a photodetector detecting the reflection light reflected by the receiving areas; wherein the light source and the partial reflection member are disposed with making the longitudinal direction of the light-emitting portion disposed substantially perpendicular to a longitudinal direction of the transmitting area as seen along an optical axis. | 05-10-2012 |
20110109963 | RELAY ZOOM SYSTEM - A relay zoom system includes, in order from an object side, a first lens group having a positive refractive power and a second lens group having a positive refractive power. Furthermore, in the relay zoom system, the first lens group and the second lens group are each made up of at least two positive lenses and one negative lens. The first lens group and the second lens group in the relay zoom system are configured so as to move along an optical axis when magnification is varied from a lower magnification edge state to a higher magnification edge state. | 05-12-2011 |

20100290029 | RANGE-FINDING DEVICE - A range-finding device includes: a light emitting unit that continuously emits measurement light to be used for distance measurement toward a measurement target object; a light-receiving unit that receives reflected light reflected by the measurement target object; a calculation unit that repeatedly calculates a distance to the measurement target object over predetermined time intervals by using the reflected light; a display unit at which an update of the distance is displayed each time the distance is calculated by the calculation unit; and a display update control unit that prohibits the update of the distance on display at the display unit and sustains the display of the previously calculated distance at the display unit according to a change in the most recently calculated distance calculated most recently by the calculation unit relative to the previously calculated distance having been calculated previously by the calculation unit. | 11-18-2010 |
20090115992 | Distance measuring apparatus - A distance measuring apparatus, which can achieve reduction in cost and size and perform measurement ranging from short-distance to long-distance accurately, includes an unit outputting first pulsed light L | 05-07-2009 |
