The present disclosure relates to a surgical microscope system and a microscope camera adapter that enable various types of adjustment in a camera adapter connecting the cameras that capture a three-dimensional image, with right and left cameras simultaneously. Of respective right and left lens groups that constitute respective focus lenses, right and left lenses between lenses closest to a side of an objective lens and lenses closest to sides of eye lenses are simultaneously moved by the same distance according to a setting value, by which focus is adjusted. The present invention can be applied to a surgical microscope system.

The present disclosure provides a continuous zoom stereoscopic microscope with an adjustable stereoscopic angle, consisting of a microscope stand, a first eyepiece module, a second eyepiece module, a first objective module, a second objective module, a first Risley prism, a second Risley prism, a first image-rotating prism, a second image-rotating prism, a drive module, a control module and an illumination module. The drive module provides preset drive values for individual liquid lenses in the liquid lens sets according to different magnifications to change the focal lengths of the liquid lenses, thereby changing the effective focal lengths of the objective module and that of the eyepiece module, and finally achieving continuous and fast zooming of the stereoscopic microscope to be adapted to different working scenarios. The control module controls the relative angle between the two wedge-angle prisms in the Risley prism, achieving the continuous adjusting of the stereoscopic angle of the stereoscopic microscope, and then acquiring stereo images with different stereo senses.

A surgical microscope for visualizing a tissue region contains an illumination device with a light source and an illumination beam path for illuminating an object region with an object plane and an observation device having an observation beam path for imaging the object region with the object plane into an observation plane. A first polarizer can be coupled into the illumination beam path and is suitable for polarizing the illumination light in a first orientation. A polarizer, which can be coupled into the observation beam path, has a second orientation at an angle between 80° and 100° relative to the first orientation. In a first mode, the light source emits illumination light in a first wavelength range between 450 nm and 550 nm, the first polarizer is coupled into the illumination beam path, and the second polarizer is coupled into the observation beam path.

An optical imaging system for imaging a target during a medical procedure, the optical imaging system involving a first camera for capturing a first image of the target, a second wide-field camera for capturing a second image of the target, at least one optional path folding mirror disposed in an optical path between the target and a lens of the second camera, and a processor for receiving the first image and the second image, the processor configured to apply an image transform to one of the first image and the second wide-field image and combine the transformed image with the other one of the images to produce a stereoscopic image of the target.
