Brief Description: This binocular microscope has two separate prisms which are "difficult to adjust." The limb is mounted on trunnions on a tripod foot. A cylindrical mounting supports the body on a bracket that attaches to one of the body tubes. Coarse focusing is by rackwork that extends a triangular sectioned bar from the main part of the limb, while fine focusing is by means of a knurled wheel operating against a spring at the top of the body mounting. The eyepieces are Huygenian and the interocular distance is adjusted by a mill-edged knob and rackwork on the eyepiece mountings. The stage is faced with glass and a brass slide-carrier is held on the stage by two spring clips. Under the stage is a rotating disc with four apertures and a large plano-concave mirror. There are no objectives with this microscope.
