The adapter includes a first connection member connected to a microscope, a second connection member connected to an imaging unit, a rotation member arranged between the first and second connection members and configured to rotate the second connection member relative to the first connection member using optical axes of the microscope and the imaging unit at a center, a control member configured to be fixed on one of the first and second connection members and control the rotation of the connection member, and a driving member configured to be engaged with the first connection member or the second connection member and change a position of the second connection member relative to the first connection member around the optical axes.

Adapter, microscope adjustment method, microscope system, and storage medium

A microscope system comprises a microscope body, a stage configured to place a slide as an observation target and move in an X direction and a Y direction. The microscope system changes an arrangement of the placed slide with respect to the stage so as to cause a direction indicated by a mark provided on the slide placed on the stage to align with one of the X direction and the Y direction of the stage.

Microscope system, control method, and program

A stage apparatus for a microscope includes a first stage provided on a mirror base of the microscope and fixed to a stage member that moves in an optical axis direction, a second stage that relatively moves over a surface of the first stage in a first direction, a third stage that relatively moves over a surface of the second stage in a second direction, the third stage having a placement portion for placing a microscope slide, and an exterior cover for covering at least a portion of the second stage and the third stage, the exterior cover being fixed to the first stage or the stage member. The exterior cover provides a space for the second stage and the third stage to move, and exposes the placement portion of the third stage.

Stage apparatus

A microscope system comprises a microscope body, an imaging unit connected to the microscope body and including an image sensor for capturing a microscopic image, and an XY stage configured to place a slide and move in an X direction and a Y direction. The microscope system changes an arrangement of the image sensor with respect to the microscope body so as to cause a direction defined by a pixel arrangement of the image sensor to align with one of the X direction and the Y direction of the XY stage.

Microscope system, control method thereof, and program

A microscope system includes a microscope body, an XY stage mounted on the microscope body and including a stage configured to place a slide as an observation target and move in an X-axis direction and a Y-axis direction perpendicular to each other, and an XY two-dimensional scale plate fixed to the stage. The XY two-dimensional scale plate is provided with a first mark that provides axis information in the X-axis direction throughout a movable range of the stage in the Y-axis direction and a second mark that provides axis information in the Y-axis direction throughout a movable range of the stage in the X-axis direction, which are used to recognize X- and Y-coordinates of the stage.

Microscope system

A microscope system comprises a microscope body, an image sensor mounted on the microscope body, and a stage that moves in an X-axis direction and a Y-axis direction, and places a slide as an observation object. The stage includes a mark used to indicate a stage reference position. The microscope system obtains positions of the stage in the X-axis direction and the Y-axis direction, and detects the stage reference position indicated by a mark provided on the stage and a slide reference position indicated by a mark provided on a slide placed on the stage. The microscope system manages the position of the stage by coordinates based on the slide reference position if the slide reference position is detected, and manages the position of the stage by coordinates based on the stage reference position if the slide reference position is not detected.

Microscope system and control method thereof

Provided is a spatial light modulator SLM and a photodetector element CMOS sensor are placed on the same chip, and the alignment thereof and a relay lens system are eliminated, whereby an optical system is reduced in cost and made compact. Specifically, provided is an optical information recording and reproducing apparatus for recording information by allowing information light and reference light to interfere with each other and reproducing the information using the reference light including: a light source; a spatial light modulator for generating at least an information light with respect to a light beam from the light source; an objective lens for irradiating a recording medium with the light beam from the spatial light modulator; and a photodetector element for receiving a reproduction light from the recording medium, in which the spatial light modulator and the photodetector element are formed on the same semiconductor substrate.

Optical information recording and reproducing apparatus

Disclosed is an optical pickup device which is small, light, and thin and which is equipped with a tilt adjusting mechanism. A lens holding body holding an objective lens and a support body supporting the lens holding body so as to allow the lens holding body to move in the focusing direction and/or the tracking direction of the objective lens, are supported at two support points on a support body mounting surface of an optical base so as to be rotatable around an axis extending in a tangential direction of an optical disk.

Optical pickup device equipped with tilt adjusting mechanism

The present invention provides an optical disk apparatus and an optical pickup which are of a thin type and capable of correcting spherical aberration, including: a semiconductor laser for emitting light; an objective lens for condensing the light from the semiconductor laser on a recording layer through a light transmission layer; at least two optical elements arranged between the semiconductor laser and the objective lend and having a predetermined refractive power; a spherical aberration correction element driving mechanism for moving at least one of the optical elements along an optical axis so as to cancel spherical aberration of imaging light on the recording layer; and a lens holder for holding at least one of the optical elements, a part of the lens folder being inserted into an opening of a cartridge and which.

Optical disk apparatus and optical pickup device equipped with spherical aberration mechanism

The disk recording/reproducing apparatus of the present invention has a magnetic head which ascends or descends between a descent position proximate to a disk recording medium housed in a cartridge and an ascent position which is separate from the medium, an ascending/descending control lever which controls ascent/descent of the magnetic head, a driving section which drives the ascending/descending control lever, and an ejecting operation section which couples with the ascending/descending control lever and can move between a position where the cartridge is allowed to be ejected out of the apparatus and a position where the cartridge is disabled from being ejected in accordance with the movement of the ascending/descending control lever, wherein the length of movement of the ascending/descending control lever is greater than the length of movement of the ejection operation section.
