Patent number: 6147800Abstract: A reflective light fluorescence system that functions on a stereo microscope with two distinct optical paths to illuminate samples that have been stained with a fluorochrome or that may exhibit autofluorescence. The stereo microscope includes a source of illumination and a filter module with two dichroic mirrors, for sending an excited wavelength of the illumination equally down both optical axes to excite the sample uniformly.

The second dichroic mirror, which is preferably about 100% dichroic, reflects 100% of the remaining portion of the illumination light down the second optical path. Thus, the sample is uniformly excited by the illumination light reflected down both optical paths. The resulting emitted signal is transmitted from the sample up through the optical paths equally.Type: GrantFiled: September 25, 1997Date of Patent: November 14, 2000Assignee: Kramer Scientific CorporationInventor: Lothar K.

Patent number: 6014166Abstract: A system operative with photon tunneling microscopy presents an image on a two-dimensional display which is perceived as a three-dimensional presentation by a person viewing the display. An optical image of the subject produced by the microscope is scanned by means of a television vidicon which converts the optical signal to an electric signal representing depth of a surface feature. The electric signal is outputted to the display wherein the image is presented as a set of line scans parallel to the horizontal axis of the display, and wherein the magnitude of the electric signal is plotted on the vertical axis of the display. A variable delay is introduced to be either increased or decreased stepwise between successive ones of the line scans. This results in a tilting of the presentation to the right or the left. Two tilted views are presented simultaneously, one to one eye and one to the other eye of an observer, to give a perception of a three-dimensional view.Type: GrantFiled: February 27, 1995Date of Patent: January 11, 2000Assignee: Polaroid CorporationInventor: John M.

Patent number: 5865829Abstract: A medical optical system includes an observation optical system for guiding light emitted from a light source to a predetermined part to be illuminated, and causing light reflected from the predetermined part to be incident on the observation optical system. The medical optical system further includes a light separator, a guide optical system, and a display unit. The light separator is disposed at an intermediate part of the observation optical system, for separating the reflected light into reflected light of a visible observation wavelength area to be passed therethrough and reflected light or fluorescent light of the other wavelength area to be extracted therefrom. The guide optical system guides the light separated and extracted by the light separator to an image pick-up device so that an image of the separated light is formed on the image pick-up device. And the display unit displays the separated light image picked up by the image pick-up device.Type: GrantFiled: November 17, 1995Date of Patent: February 2, 1999Assignee: Kabushiki Kaisha TopconInventor: Nobuaki Kitajima

Patent number: 5825534Abstract: The invention relates to a stereoendoscope having a sight line folded relative to the tube axis. The endoscope includes a distal front optic having a deflecting prism 4b. The deflecting prism 4b is mounted between a component 4a having a negative refractive power and a proximal component 4c having a positive refractive power. The inlet pupils 11 of the viewing component are imaged demagnified in the reflecting prism 4b by field optics (7, 7', 13) and transmitting optics (8, 8', 14). In this way, the beam can be guided free of vignetting without field cropping for both stereo channels through the endoscope tube and through the reflecting prism 4b even for a large object field angles and without image cropping. The endoscope tube 2 and the viewing component 1 are rotatable with respect to each other about the optical axis 12 within the endoscope tube 2 so that the line of sight can be changed for a viewing component fixed in space. The stereo basis remains for a rotation of the endoscope tube 2 fixed in space.Type: GrantFiled: September 7, 1995Date of Patent: October 20, 1998Assignee: Carl-Zeiss-StiftungInventor: Fritz Strahle

Patent number: 5822114Abstract: A stereoscopic microscope comprising an objective lens system and a variable magnification optical system which are disposed coaxially with each other in addition to an eyepiece optical system, and configured so as to permit stereoscopic observation of an image of an object by leading, to right and left eyes of an observer by way of the eyepiece optical system, rays having passed through portions apart from optical axes of the objective lens system and the variable magnification optical system. This stereoscopic microscope has a length as measured from the observer's eyes to the object to be observed which is shortened by disposing at least two reflecting members in the variable magnification optical system for bending an optical path in the variable magnification optical system.Type: GrantFiled: September 3, 1997Date of Patent: October 13, 1998Assignee: Olympus Optical Co., Ltd.Inventor: Toyoharu Hanzawa

Patent number: 5748367Abstract: An illuminating device for a stereo microscope having an objective with variable imaging focal intercept includes first coupling mechanism, which effects a coupling between the imaging focal intercept of the objective and the likewise adjustable focal intercept of the illuminating optical system, separate from the observation optics, in such a manner that the illuminating focal intercept is in agreement with the imaging focal intercept of the objective. Moreover, adjusting mechanism is provided for the defined adjustment of the diameter of the illuminated field. In particular, the illuminating device is suitable for a surgical microscope.Type: GrantFiled: October 18, 1995Date of Patent: May 5, 1998Assignee: Carl-Zeiss-StiftungInventors: Christian Lucke, Gunther Summerer, Hartmut Gartner

Patent number: 5729382Abstract: A stereoscopic microscope having right and left eyepiece lens systems for observation of two aerial images formed with parallax. The stereoscopic microscope comprises a main body housing and an eyepiece body housing which comprises an optical system ranging to aerial images formed at locations nearest the observer's eyes and eyepiece lens systems including transmission type light diffusing devices which are disposed in the vicinities of the aerial images formed at the locations nearest the observer's eyes, thereby permitting enlarging the exit pupils and performing stereoscopic observation with little fatigue.Type: GrantFiled: July 7, 1995Date of Patent: March 17, 1998Assignee: Olympus Optical Co., Ltd.Inventors: Kazuo Morita, Toyoharu Hanzawa

Patent number: 5689365Abstract: A stereoscopic-vision endoscope having an objective optical system consisting of a front optical system having a single optical axis including a field conversion optical system, and a rear optical system including optical systems that have a plurality of optical axes. A light beam is received from the front optical system so as to form images on the optical axes, and thus form a plurality of images. The front and rear optical systems can be turned relative to each other. Thus, a magnitude of parallax permitting a sufficient sense of three-dimensionality can be provided, and the postures of images can be corrected responsively to a change in direction of view resulting from the rotation of an insertional part.Type: GrantFiled: September 11, 1995Date of Patent: November 18, 1997Assignee: Olympus Optical Co., LtdInventor: Susumu Takahashi
