ABSTRACT:
This invention relates to a stereo microscope comprising light collection means for collecting two angularly separated beams of rays from an object, a light path for each beam to guide said beam from said light collection means to an eye-piece and magnification means associated with each light path, whereby on viewing simultaneously the beam leaving each light path, a magnified stereoscopic image of the object is obtained, characterized in that the light collection means for each path comprises a first reflecting surface, and a second reflecting surface in spaced relationship with a first reflecting surface, in which each first surface is adapted to receive and reflect a beam from an object to said second reflecting surface, the beams reflected from the second reflecting surface being disposed along substantially spaced parallel axes.
