content: Bausch & Lomb introduced their Physician’s microscope in 1877, boasting that it was “firm and well balanced” and well adapted “to the use of physicians and students.” The stand and case cost $40; with two objectives and camera lucida it cost $65. Ernst Gundlach, the Prussian immigrant who had become superintendent of the firm’s new microscope department in 1876, was largely responsible for the form.
label: Description
content: This is an example of the modified version that the firm brought out in 1884. It is a compound monocular with coarse and fine focus, double nosepiece (one missing), rectangular stage, inclination joint, sub-stage diaphragm, sub-stage mirror, and curvaceous base. The tube and limb are brass; the base is black iron; the stage is heavy glass. The inscription on the stage reads “BAUSCH & LOMB OPTICAL CO.” That on the arm reads “PAT. OCT. 3. 1876 / PAT. OCT. 13, 1885.”
