In order to allow the assistant also to make an observation of the same region of the object as by the surgical operator in the form of a normal and clear stereoscopic image, and to enable the size of the barrel as well as the price to be about the same as that of an ordinary surgical microscope having two optical axes, the surgical microscope of the invention is arranged so that by the employment of two pairs of prisms each having a polarized light beam splitter section and a total reflection surface, a pair of operator's observational optical systems and a pair of assistant's observational optical systems are used partly in common, and one of the polarized beams so split by the polarized beam splitter section is utilized as the operator's observational light, and the other is utilized as the assistant's observational light. One pair among the two pairs of prisms is constructed as a first stereoscopic view adapter, and the other pair as a second stereoscopic view adapter, and the common portion of the observational optical systems mentioned above is constructed in the form of a barrel, and all of these constituent parts are removably coupled to each other. |
