Pacini-type compound microscope invented by Filippo Pacini and made in the workshop of Giovanni Battista Amici. On a semicircular base are inserted two tapered pillars holding an oval stage. Alongside it, a square-sectioned telescopic pillar supports the body-tube; its vertical position is adjusted for focusing with a screw controlled by a knob. A graduated disk controls micrometric motion of the stage plate. Below the stage are the illumination mirror and a condenser lens. An Amici prism is fixed on an articulated arm to the front of the stage. The body-tube, which lacks the eyepiece, is tilted and attached to the support by means of a total-reflection prism that deflects the rays from the objective into the eyepiece. The box contains no accessories. Provenance: Lorraine collections.
