An adjustable light source device for a stereoscopic surgical microscope has a circuit board and multiple light sources. The circuit board is mounted in an outer casing of the stereoscopic surgical microscope and is electrically connected to a host computer of the stereoscopic surgical microscope. The light sources are electrically mounted on the circuit board at spaced intervals around two objective lenses of the stereoscopic surgical microscope and extend out of the outer casing. Each one of the light sources has a wavelength different from wavelengths of the other light sources and is controlled to emit light by an operating set of the stereoscopic surgical microscope via a program processing interface of the host computer sending signals to the circuit board. The adjustable light source device can emit lights with different wavelengths to enable the stereoscopic surgical microscope to capture clearer images for various surgical divisions.

A surgical microscope system includes a surgical microscope. In the surgical microscope, variable power optical systems are arranged horizontally to fold optical paths, thereby reducing a vertical size between eyepieces of the surgical microscope and a lower end of the same and expanding a working space under the surgical microscope. A camera is attached to an upper part of the surgical microscope to free a side face of the surgical microscope so that an accessory such as a fluorescent camera is attached to the side face.

A lightweight 3D stereoscopic surgical microscope has a body, a robot set, an image set, and an operating set. The body has a wheel seat, a housing mounted on the wheel seat, and a host computer mounted in the housing. The robot set is connected to the body and has a base mounted on the housing, a transversal lever mounted on the base, a lifting arm connected to the transversal lever, and a rotating arm connected to the lifting arm. The image set is connected to the robot set and has an outer casing connected to the rotating arm, at least one objective lens mounted in the outer casing, a main display screen mounted on the outer casing, an auxiliary display screen mounted beside the body. The operating set is connected to the robot set, is connected to the body and the image set and has two operating bars.

An adjustable dual-lens device for 3D stereoscopic surgical microscopes has an outer casing, an image set, and an adjusting set. The image set is mounted in the outer casing and has two lenses. The lenses are pivotally mounted in the outer casing at a spaced interval. The adjusting set is mounted in the outer casing and has two adjusting units. Each adjusting unit has a driving motor, a cam, and a limiting element. The driving motor is mounted in the outer casing adjacent to one of the lenses and has a driving shaft. The cam is eccentrically mounted around the driving shaft and is pressed against the lens that is adjacent to the driving motor. The limiting element is connected to the outer casing and the corresponding lens to enable the corresponding lens to press against the cam.

A novel method is disclosed to allow for the simultaneous capture of image data from multiple depths of a volumetric sample. The method allows for the seamless acquisition of a 2D or 3D image, while changing on the fly the acquisition depth in the sample. This method can also be used for auto focusing. Additionally this method of capturing image data from the sample allows for optimal efficiency in terms of speed, and light sensitivity, especially for the herein mentioned purpose of 2D or 3D imaging of samples when using a tilted configuration as depicted in FIG. 2. The method may be particularly used with an imaging sensor comprising a 2D array of pixels in an orthogonal XY coordinate system where gaps for electronic circuitry are present. Also other imaging sensor may be used. Further, an imaging device is presented which automatically carries out the method.
