Publication number: 20070081232Abstract: A microscope system according to the present invention comprises a stage on which a specimen is placed, an image forming optical system that forms an image of the specimen placed on the stage, an image-capturing device that captures the image of the specimen formed by the image forming optical system, a focused position detection device that detects a focused position for the specimen based upon the specimen image captured by the image-capturing device and a focused position storage device that stores in memory the focused position detected by the focused position detection device. The focused position detection device sets a search range centered around the focused position stored in memory at the focused position storage device and detects the focused position anew by causing the stage and the image forming optical system to move relative to each other over the search range thus set each time a focusing operation is executed.Type: ApplicationFiled: December 5, 2006Publication date: April 12, 2007Inventor: Yasushi Ogihara

Publication number: 20050105174Abstract: A microscope system includes a plurality of objectives with different magnifications and a focus adjustment device that adjusts a focus position of the objective. The focus adjustment device starts executing the focus adjustment operation as the user operates the AF button. Even when no instruction to start the focus adjustment operation according to operation of the AF button is issued, the focus adjustment operation can be started when the user operates the objective selection switch to switch over from the low magnification objective to the high magnification objective.Type: ApplicationFiled: October 1, 2004Publication date: May 19, 2005Inventors: Yasushi Ogihara, Ryosuke Komatsu

Patent number: 6804049Abstract: A microscope device includes a support member which supports a specimen, a first optical system which generates an image of a partial region upon the specimen, a second optical system which generates an overall image of the specimen, an imaging device which photoelectrically detects the images which are generated by the first optical system and by the second optical system, and a changeover mechanism which changes over between a first path from the specimen via the first optical system to the imaging device and a second optical path from the specimen via the second optical system to the imaging device. The support member, the first optical system, the second optical system, the imaging device, and the changeover mechanism are all housed within a case of the microscope device.Type: GrantFiled: November 5, 2001Date of Patent: October 12, 2004Assignee: Nikon CorporationInventors: Katsumi Ogino, Yasushi Ogihara, Chikaya Iko

Publication number: 20020176160Abstract: A specific value for the magnification factor to be achieved for a specimen image is input to observe the specimen through a microscope. An optical system magnification factor and an electronic zoom magnification factor are calculated so as to achieve this specific value. When there are a plurality of optical systems with varying magnification factors, the optical system that achieves the calculated magnification factor is inserted at an observation optical path. When outputting image signals by capturing an image of the specimen formed by the optical system, the specimen image is obtained at the electronic zoom magnification factor that has been calculated. As a result, it is possible to obtain an image of the specimen which achieves a magnification factor determined in conformance to the product of the magnification factor of the optical system and the electronic zoom magnification factor.Type: ApplicationFiled: March 29, 2002Publication date: November 28, 2002Applicant: Nikon CorporationInventors: Akitoshi Suzuki, Yasushi Ogihara

Patent number: 6222671Abstract: An optical element switching device capable of quickly and reliably switching among optical elements. The optical element switching device includes a fixed guide section mounted on a housing, and a movable guide section mounted movably relative to the fixed guide section and provided with more than three optical elements. By moving the movable guide section, one of the optical elements is selectively inserted into the optical path. The optical element switching device further includes a restricting mechanism for limiting the number of optical elements which can be inserted into the optical path by restricting the movement of the movable guide section.Type: GrantFiled: November 12, 1997Date of Patent: April 24, 2001Assignee: Nikon CorporationInventor: Yasushi Ogihara
