Abstract: A microscope includes an observation optical system having at least an optical axis, an eyepiece unit, and an objective lens unit, and a frame for arranging the observation optical system thereon. The frame has a Y-shaped body, constituted by forming a first foot extending along the optical axis, a second foot extending along the optical axis, and a base located immediately under the optical axis to substantially form a Y shape within an installation surface, and an arm member connected to the Y-shaped body and having at least the eyepiece unit and the objective lens unit mounted thereon.
Abstract: An optical system for a scanning probe microscope provides both an optical on-axis view and an optical oblique view of the sample by means of two optical paths each providing an image to a CCD camera via an auto-zoom lens. A shutter alternately blocks the image of either view from reaching the auto-zoom lens. The CCD camera provides the optical image to a video display which also displays the scanning probe image, thus eliminating the need for eyepieces and allowing easy viewing of both the optical and scanning probe images simultaneously.

Abstract: A surgical microscope apparatus comprising a supporting device for suspending a microscope, a detecting device for detecting a location of a pupil of an observer relative to an observing pupil of the microscope and a drive controller for automatically moving the microscope, on the basis of a result detected by the detecting device, so that the observing pupil of the microscope is coincident with the pupil of the observer. This surgical microscope apparatus requires no manual handling for shifting the microscope and permits a continuous observation of a visual field without fail.
Abstract: A direct-view stereoscopic confocal microscope including a light source, an aperture plate, image collector, and first and second vibrators. The light source is used for illuminating a portion of a specimen and the aperture plate is used for passing a portion of the light emanating from the light source onto a portion of the specimen. The image collector is optically coupled to the illuminated portion of the specimen and acts to separate the image created by the illuminated portion of the specimen from the light illuminating the specimen. A first vibrator is coupled to the specimen for vibrating the specimen along a first axis and the second vibrator is coupled to the image collector, and synchronized with said first vibrator, for vibrating the collecting means along a second axis.

Abstract: An optical viewing system is described which permits viewing through a microscope at a more comfortable and advantageous angle. The device of the invention attaches between the body of the microscope and the eye piece and can be either rigid in its configuration or adjustable to permit varying angles of view. Various optical systems ca be employed within the viewing device of the invention to preserve optical integrity.
Abstract: A confocal scanning optical microscope in which a specimen under test is simultaneously scanned with two distinct spots or slits of illumination and two output beams emitted from the specimen due to reflection or fluorescence are descanned and passed to separate stationary confocal apertures and detectors.
Abstract: An oblique viewing system is attachable to a microscope to selectively obtain a perpendicular view (along the optical axis of the microscope) and oblique views of surfaces of objects under inspection. The attachment is connected to the microscope's objective end by a coupling on a housing containing the viewing system. The system includes a folding mirror and an oblique viewing mirror, spaced from the folding mirror and having its reflecting surface facing the object under inspection. A latching or a toggle mechanism, connected to a rotatable support for the folding mirror, enables that mirror to be set in either of two positions, one out of the way of the perpendicular path to provide a perpendicular view and the other to orient the reflecting surface thereof to face the reflecting surface of the oblique viewing mirror along an optical axis there between.
Abstract: The invention is an inverted microscope with a housing having multiple integrated ray paths leading from the specimen being examined to (a) the viewer/operator and (b) one or more auxiliary ports used for image recording and/or measurement by accessories such as cameras and video recorders. The microscope lens is positioned below the specimen stage; and, positioned below the lens, is a simple reflector which deflects the combined rays from the lens diagonally upward toward the viewer at exactly the same angle at which the viewer looks into the microscope's binocular eyepieces. The position of this simple reflector is the lowest point in the unit's paths of rays, thereby significantly lowering the lens turret and, therefore, the specimen stage to a relatively low, ergonomically-appropriate position. The optical arrangement is simple and compact, minimizing the number of deflections in the path of the viewing rays.
Abstract: A microscope optical system having an objective lens, an observing direction converting prism bending a beam of light from the objective lens in a predetermined direction, and an eyepiece for observing an image formed by the beam of light bent in the predetermined direction comprises a first prism having the same bottom angle as the observing direction converting prism, replaceable with respect to the observing direction converting prism, a loop optical path comprised of an odd number of reflecting members for conducting the light beam transmitted by the first prism in the predetermined direction, and a photographic lens provided in the loop optical path. Thus, the microscope optical system has important advantages in practical use that where image recordings are made in photography and video, the field range and the position of a photographic image can be observed as they are through the eyepiece, magnification is variable without rendering the lens barrel large, and the structure is simple with low cost.

Abstract: An apparatus for inspecting the top and bottom surfaces of a tape or sheet has a device to magnify the surface of the tape or sheet, with its objective lens disposed to face the top surface of the tape or sheet. The apparatus also has an optical transmittion system that transmits an image of the bottom surface of the tape or sheet through a focusing unit and four reflectors, each of which is adapted to bend the path of light rays 90 degrees. Of the four reflectors, one that faces the objective lens is retractable from the light-ray path in the optical transmission system. The reflector facing the objective lens may be a half-coated mirror. Fixed in the light-ray path in the optical transmission system, the half-coated mirror is not retractable.
Abstract: An optical attachment for a microscope which comprises a relay lens, a field lens, and at least four mirrors forming a square, closed optical path. The relay lens is set between the third mirror and the fourth mirror, the field lens between the first mirror and the second mirror, while the field lens is set on the image erected by the relay lens, the objective of the microscope is so set as to focus on the image erected by the field lens, and the first mirror is made replaceable outside of an optical path formed in front of the objective of the microscope.
