摘要:
An optical device, in particular a microscope (1), that includes a beam path in which is arranged at least one deflection element (5, 6a to 6f) for deflecting the beam path, at least one vibration sensor (34) being arranged in or on the optical device; at least one of the deflection elements (5, 6a to 6f) including a mirror having a controllably deformable mirror surface (50); and a control unit (32) being provided that, as a function of the output signal of the vibration sensor (34), applies control to the at least one deflection element (5, 6a to 6f) in order to adjust the mirror surface (50) in such a way that vibrations of the optical device are compensated for by a correspondingly opposite-phase adjustment of the mirror surface (50).

An assistant microscope add-on device for a surgical microscope (1) comprises an objective (22) inclined relative to an object plane (10) with an object field (10′), wherein the objective defines an objective plane (22′) and an objective axis (16′) perpendicular thereto forming an angle α larger than 0° to the surface normal of the object plane (10). A tube (23) and an eyepiece (24) having an eyepiece lens (27) defining an eyepiece plane (27′) and an eyepiece axis (35) perpendicular thereto. Due to the oblique viewing angle, an intermediate image plane (26) to be imaged by the eyepiece (24) is inclined relative to the objective plane (22′). The resulting aberration is eliminated by the eyepiece axis (35) and the objective axis (16′) forming an angle β of larger than 0°, wherein the angle β is so chosen that the eyepiece axis (35) is substantially perpendicular to the intermediate image plane (26). Consequently, the object field (10′) is imaged free of distortion and sharply across the entire image area.

An optical device for imaging a specimen (16) has a main objective (2) and a device (120) for modifying depth of field, the device (120) representing a micromirror array (5′) having micromirrors (50) that are individually controllable and adjustable as to their spatial orientation. In addition to the increase in depth of field, a variable objective can also be produced. The invention is particularly suitable for use in a microscope where deflection of the observation beam path is present.
摘要:
An assistant microscope as an add-on device for a surgical microscope (1) comprises at least one objective (22) that is inclined relative to an object plane (10) with an object field (10′), in which the objective defines an objective plane (22′) and an objective axis (16′) perpendicular thereto forming an angle α of larger than 0° to the surface normal of the object plane (10). The light microscope further comprises a tube (23) and at least one eyepiece (24) having at least one eyepiece lens (27) which defines an eyepiece plane (27′) and an eyepiece axis (35) arranged perpendicular thereto. Due to the oblique viewing angle onto the object plane (10), an intermediate image plane (26) to be imaged by the eyepiece (24) is inclined relative to the objective plane (22′), on a conventional microscope it no longer corresponds to the nominal intermediate image plane. According to the invention the aberration caused by this is eliminated by the eyepiece axis (35) and the objective axis (16′) forming an angle β of larger than 0°, wherein the angle β is so chosen that the eyepiece axis (35) is substantially perpendicular to the intermediate image plane (26). In this way, the object field (10′) is imaged free of distortion and sharply across the entire image area.

The invention concerns a microscope (5) with a stand (1), in which an ARES component (71) is arranged for vibration compensation. A steady subject image is thereby guaranteed in particularly effective fashion.
摘要:
A surgical microscope system (1, 2, 3, 4, 5, 6) having a display (7a-7e). Data essential for the surgical procedure, for example video images, are displayed in the observer's immediate field of view, thus making it unnecessary to turn one's head away from the surgical visual field. Because of its optical properties, the display (7a-7e) can also be attached, for example, on the curved exterior of the microscope body (2) or also on an X-Y coupling (6) that may be present. An rigid OLED display or a flexible OLED display is preferably used.
