Bausch & Lomb Compound Monocular
Designated the Universal Model by the Bausch & Lomb Optical Company, this inverted microscope was introduced in 1886. Most of the microscope is constructed of brass and it measures 14 1/2 inches tall.
The circular-tripod base has been weighted to add stability to the microscope, and supports a tubular pillar that holds the stage, body, and eye tube on an angular arm. The stage is circular brass ring with a heavy glass center that is screwed into a limb plate attached to the arm. Also attached to the arm is a smaller sliding rod that supports a double mirror on a short shaft to reflect illumination through a specimen and into the objective. The objective is mounted above the microscope body, which consists of a prism box with an attached nosepiece and a threaded opening into which the drawtube containing the eyepiece is screwed. Focus is achieved by a rack mechanism that is controlled by a knurled knob that moves the microscope body up and down with respect to the stage.
