A kind of surgical operation microscope, including primary mirror shank, the binocular lens tube that is connected with the primary mirror shank, the primary mirror mirror
Body can roll to each side in the vertical plane of the binocular optical axis of the binocular lens tube using the binocular optical axis as axial its is swung,
Big objective lens, zoom group are provided with the primary mirror shank；Small objective lens, eyepiece group are provided with the binocular lens tube,
The surgical operation microscope further includes beat relay system, and the beat relay system includes the first imaging microscope group, turns to rib
Mirror and the second imaging microscope group, the described first imaging microscope group, the second imaging microscope group are relatively fixed setting, the steering microscope group
Intermediate image only to described first imaging microscope group is once turned to, be imaged light along the big objective lens, zoom group,
First imaging microscope group, be observed after turning to prism, the second imaging microscope group, small objective lens and eyepiece group.
Preferably, described first imaging microscope group, the focal length of the second imaging microscope group are on the occasion of and between 12 ~ 88mm.
Preferably, the reflecting surface of the relatively described steering prism of the first imaging microscope group, the second imaging microscope group is symmetrical.
Preferably, described first imaging microscope group by least one positive lens groups into.
Preferably, described second imaging microscope group by least one positive lens groups into.
Preferably, the steering prism is that can be turned into the inverted image of the intermediate image of first relay lens
The roof prism of erect image.
Preferably, the big objective lens, zoom group and the first imaging microscope group are set along primary optic axis；Described second
Imaging microscope group, small objective lens are set along the second optical axis.
It is further preferred that the steering prism is arranged on the primary optic axis, the infall of the second optical axis, it is described
Primary optic axis, the second optical axis it is perpendicular.
The present invention operation principle be：
The imaging light of object is by coming out parallel rays after the big objective lens, zoom group of surgical operation microscope, by the first imaging
Microscope group carries out an intermediate image, and intermediate image overturns the inverted image of intermediate image after being turned to by the primary event of image rotation prism
Enter the second imaging microscope group into erect image, the parallel rays that the second imaging microscope group comes out is observed after small objective lens, eyepiece group.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
The present invention reduces the diverging of light by carrying out an intermediate image in beat relay system；Both sides lens group also without
Need relative motion so that beam divergence reduces, while retains the advantages of visual field is unobstructed.
