Provided is a medical observation apparatus including: a columnar microscope unit configured to image a minute part of an object to be observed with magnification and thereby output an imaging signal; and a support unit including a first joint unit holding the microscope unit in a rotationally movable manner around a first axis parallel to a height direction of the microscope unit, a first arm unit holding the first joint unit and extending in a direction different from the height direction of the microscope unit, a second joint unit holding the first arm unit in a rotationally movable manner around a second axis orthogonal to the first axis, and a second arm unit holding the second joint unit. In a plane passing through the first and second axes, a cross section of the microscope unit, the first and second joint units, and the first and second arm units is included in a circle that has a center at a focus position of the microscope unit and passes through an end point of the first joint unit that is at the maximum distance from the focus position. Thus, when imaging an object to be observed and displaying the image, the user's visual field for observing the displayed image can be sufficiently ensured.

A slip-resistant eyewear system comprising an eyewear frame generally comprises first and second hinges coupled to the eyewear frame which are also coupled to first and second tension adjusters. First and second bows are coupled to first and second tension adjusters. The system may comprise an eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

Disclosed are a mass transfer device and a mass transfer method. The mass transfer device includes a laser (100), a coupling unit (200), an optical fiber (300), a ceramic ferrule (400), and a coaxial focusing structure (500) which are sequentially connected. A laser light output by the laser (100) is coupled into the optical fiber (300) through the coupling unit (200). The coaxial focusing structure (500) is fixed to an end of the ceramic ferrule (400). An end of the optical fiber (300) is inserted into the ceramic ferrule (400).

A medical observation system 1 is provided with an imaging unit 21 which captures an image of a subject to generate a captured image, a distance information acquiring unit which acquires subject distance information regarding subject distances from a specific position to corresponding positions on the subject that correspond to at least two pixel positions in the captured image, and an operation control section 264c which controls at least any of the focal position of the imaging unit 21, the brightness of the captured image, and the depth of field of the imaging unit 21 on the basis of the subject distance information.

A stand for a surgical microscope and a method for optimizing an assembly space of a surgical microscopy system are provided. The stand includes a base part, a stand part forming a c-shape structure, having a first end and a second end, and being mounted on the base part at the first end. The stand part has a hollow structure with reinforcements arranged within the hollow structure and the reinforcements extend vertically through the entire hollow structure. The stand part may include a first stand part element and a second stand part element, and the first and second stand part elements are arranged at a horizontal distance relative to one another and form together the c-shape structure. The method includes relocating electronic components from the arms to an area of the stand part thereby shifting a center of gravity of the stand.

A method includes rotating a mirror assembly in a first direction using an actuator. The mirror assembly is rotationally coupled to a base and includes a mirror. A first end of the mirror is rotationally coupled to the base, and a second end of the mirror is not supported by or attached to another structure. The method also includes rotating a reaction inertia assembly in a second direction opposite the first direction using the actuator. The reaction inertia assembly is rotationally coupled to the base. The method further include restricting movement of the mirror assembly and the reaction inertia assembly in multiple degrees of freedom using multiple flexures.
