Pacini-type compound microscope matching exactly the one described by Filippo Pacini in his 1845 paper. 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, a condenser lens, and a disk with several diaphragms. The body-tube is inclined and attached to the support by means of a total-reflection prism that deflects the rays from the objective into the eyepiece. Provenance: Lorraine collections.
