Technical problem to be solved in the utility model is: a kind of comparator microscope is provided, this comparator microscope is when cutting the visual field observation, the left and right sides image mosaic goodness of fit is good, and different eyepiece enlargement ratios can both form a cut-off rule clear, that width is moderate down.

Solve this technical problem, the technical solution of the utility model is: a kind of comparator microscope, comprise base, pontic, the eyepiece mechanism at the objective table of the symmetry between pontic and base and pontic top, have the prism of turning to mechanism and relay lens mechanism in the pontic cavity, left and right fields of vision cut-off rule governor motion, described left and right fields of vision cut-off rule governor motion comprises left edge of a knife plate, right edge of a knife plate, with left edge of a knife plate and all affixed edge of a knife plate connecting link of right edge of a knife plate, edge of a knife plate connecting link is connected with horizontal mobile mechanism, and described left edge of a knife plate and right edge of a knife plate are the metal finish part.

Described horizontal mobile mechanism is a pinion and rack.

Has middle clamp plate in the described pontic, described optical inversion prism mechanism comprises that two couple that described middle clamp plate is arranged up and down turns to prism, described optical inversion lens mechanism is positioned at the middle part of described middle clamp plate, and described left and right fields of vision cut-off rule governor motion turns between the prism two couple that middle clamp plate is arranged up and down.

Described relay lens mechanism comprises the relay lens seat of solid of revolution and the relay lens group in the relay lens seat, and the relay lens seat is fixed in the top of described middle clamp plate.

Be connected with gangbar between the objective table of described two symmetries, gangbar is fixedlyed connected with the interlock knob that moves up and down with its move left and right of adjusting.

The utility model adopts such structure, the left edge of a knife plate and the right edge of a knife plate of left and right fields of vision cut-off rule governor motion are the metal finish part, can satisfy the accuracy requirement of instrument, and enough rigidity and intensity are arranged, when transportation, use, can not damage, overcome the defective of the cutting crest line of prior art, when cutting the visual field observation, the left and right sides image mosaic goodness of fit is good, and different eyepiece enlargement ratios can both form a cut-off rule clear, that width is moderate down; The left and right fields of vision cut-off rule governor motion that can move horizontally can be compared to left and right sides two articles at diverse location, realizes left monoscopic, right monoscopic, cutting visual field, overlapped fov observation; The employing of relay lens group makes comparator microscope have the space of placing photographic device.
