- The Universal microscope that Bausch & Lomb introduced in 1884 was similar to the popular Investigator but larger and heavier and equipped with several new features. The basic stand with case cost $55; with two objectives and camera lucida it cost $80. This example of that sort. It is a compound monocular with coarse and fine focus, bullseye condenser attached to the body, large circular mechanical stage, inclination joint, sub-stage condenser and iris diaphragm, sub-stage two-sided mirror, and tri-leg base. The inscription on the stage reads “BAUSCH & LOMB OPTICAL CO.” That on the arm reads “PAT. OCT. 3 1876.”
