Abstract:
Methods and systems are provided herein for a surgical optical system having a heads up display including, in accordance with various embodiments, an optical device, an image sensor optically coupled to the optical device to acquire image data from a field of view of the optical device, and a display device configured to display an acquired image representing the image data acquired by the image sensor.
Abstract:
An observation optical system has an objective system and an eyepiece system in the order from the object side. The objective system includes, in the order from the object side, a first group having a positive power, a second group having a positive power, and a third group having a negative power. The objective system has an inverting optical system. The eyepiece system includes, in the order from the object side, a fourth group having a positive power and a fifth group having a positive power. The third group and the fourth group move in directions separating from each other along an optical axis to thereby perform variable power from a low magnification to a high magnification, and also the following conditional expression is satisfied: 0.28
Abstract:
A microscope head includes a housing having a pivot axis located generally at a center of gravity of the housing. At least one handle is connected to the housing coaxially with the pivot axis. Mounting structure is for rotatably mounting a support arm coaxially with the pivot axis. A tension control ring is attached coaxially with the pivot axis for varying a rotation force required to rotate the housing with the handle about the pivot axis. A magnification selector mechanism is connected to the housing coaxially with the pivot axis.
Abstract:
A surgical retractor includes a plurality of cameras integrated therein. One such retractor includes a tubular retractor and an insert supporting said plurality of cameras can be disposed within a tubular retractor.
Abstract:
A microscope includes a fixed section, a moving section that is movable with respect to the fixed section, and a bellows type expandable light shielding section provided between the fixed section and the moving section, wherein bending sections of the light shielding member are thicker than wall sections of the light shielding member.
Abstract:
A tube attachment for microscopes which facilitates visual microscope work particularly over extended periods and which can be used universally for different types of microscopes and, at the same time, can be produced economically using simple manufacturing techniques, it is suggested that a tube attachment is constructed as a holder which can be adjusted with respect to height and, optionally, with respect to angle and can be fastened directly to a binocular tube of a microscope. The holder includes two carriers which are displaceable axially relative to one another and which have a forehead rest and a chin support or one carrier with the forehead rest for a user, and devices are provided at the carriers for clamping the adjusting movements of the carriers.
Abstract:
An apparatus and process for visual observation and measurement of aggregated, granular and floating or suspended particles samples, which are gravitationally separated is disclosed. The first part of apparatus is the horizontally focused binocular microscope with vertical positioning. The second part of the apparatus is the revolving test tube holder with vertical positioning and rubber ring for soft tube position fixing. The process is consisting in horizontal focusing on the visual sample analyzing it in liquid. The difference from conventional process of sample analyzing is that in vertical position the gravitationally separated fractions of the sample will be not disturbed during the analysis and study of the sample. This will make possible both to study the micro-granulometry samples under horizontally focused binocular microscope and to use different liquids for gravitational separation of particles and granules without contaminating the environments and degrading working conditions.
Abstract:
A microscope lens barrel includes an input port where observation light enters the microscope lens barrel; a plurality of output ports which the observation light goes out of the microscope lens barrel; an optical-path switching mechanism which selectively switches an optical path of the observation light to guide the observation light from the input port to at least one of the output ports; and a supporting part which supports the optical-path switching mechanism. The input port, the output ports, and the supporting part are integrally formed as a tubular body frame so that the input port, the output ports, and the supporting part are arranged at respective center positions of sidewalls of the tubular body frame.
Abstract:
An adjustable microscope tube (MT) for a microscope (T) comprises, in this order, along its beam path coming from an entrance to the microscope tube (MT): an optical system (S), which images a first intermediate image to infinity; at least one deflecting element (U1, U2), which folds the parallel beam path following the optical system (S), and collecting optics (SO), arranged following the deflecting element (U1, U2) in the beam path, for imaging the first intermediate image, which has been imaged to infinity, onto a second intermediate image, wherein the length of at least one portion (A1, A2) of the folded, parallel beam path can be changed by displacement of the deflecting element (U1, U2) relative to the optical system (S).
Abstract:
An inverted microscope (1) equipped with an ergotube (9) is disclosed. The ergotube (9) substantially comprises an eyepiece (9a) and a tube housing (9b). The microscope beam path (30) defined by the inverted microscope (1) is of U-shaped configuration. The U-shaped microscope beam path (30) is deflected into the eyepiece (9a) by a single deflection element (74) that is embodied as a pivotable mirror.
