In addition, this Pacini model has an Amici prism with an aperture on a hinged brass arm that protrudes from the front of the stage. An oval stage housing is positioned at the top of the columns and has plenty of room to accommodate a wide spectrum of specimens. The back portion of the stage is supported by a large rectangular brass limb, which contains a trapeze-sectioned bar carrying the arm to which the body tube is attached. This inner bar is attached to a locking screw that controls a long vertical iron screw serving as the fine focus mechanism through a knurled wheel positioned under the base. Below the stage is a set of four apertures and a single-lens condenser that can travel up and down on a brass rod.
Light is projected into the condenser lens by means of a plano-concave mirror.
