Vintage Antique Bausch & Lomb Stereo Microscope
This microscope was originally constructed in compliance with a generally expressed demand for a simple, relatively low-price and well-made instrument, which is adapted to every grade of work, and claim that in it we have a model which possesses, in an eminent degree, these qualities. Probably no low-price instrument has ever been offered the public, which has been so favorably received and met with such ready sale as this. It is of chaste design, its parts are all calculated to bear the strain of every-day work, and on this account and because of its simplicity, it may be used by inexperienced hands, without detriment or injury to it.
This microscope especially recommends itself by requiring a smaller pecuniary outlay than any of similar construction, and may be supplied with valuable additions, such as our revolving and glass stages, mirror-bar with adjustable mirror and sub-stage, all of which greatly increase the efficiency and add but little to the price of the instrument. The tripod base, pillars and arm, are neatly japanned; the axis is arranged with strong bearings to allow inclination of the body to any angle.
Coarse adjustment is by perfect rack and pinion, provided with tightening screws; fine adjustment by a delicate micrometer screw, acting on our patent movement.

The instrument also bears Serial Number , which is engraved on the side of the brass ocular holder on the top of the body tube see image. Included with this listing is a cut from the Catalog that shows one version of this latter instrument that has the screw mounted Abbe condenser in the substage. The unit featured here lacks that feature, but has an iris diaphragm and so is one of the more simplified versions of the Model APS.
In the folded position, the two legs of the base pivot and come together to form a rectangular block that allows the instrument to be nicely nested into its wood case. Rising from the base is a nicely sculpted fixed vertical arm or limb that supports the stage and the rest of the instrument. This instrument is equipped with a 92mm by 76mm rectangular Vulcanite covered fixed stage. The stage has a 15 mm central aperture and includes a pair of removable slide clips atop the stage.
Completing the substage illumination system is 50mm plano-concave yoke mounted mirror on a swinging arm that allows for oblique illumination. Coarse focus is by a rack and pinion assembly at the leading edge of the limb. A pair of nicely machined extra-large 40mm diameter brass milled heads controls the coarse focus. Fine focus is by means of pair brass micrometer knobs mounted on the side of the limb below and behind the coarse focus knobs. The fine focus mechanism is very precise in concert with the US Patent description.
The body tube of the microscope is equipped with a drawtube that is marked with a millimeter scale. At the top of the drawtube is a brass ocular holder.
It has some nice features: Original Bausch and Lomb objective marked 43X 4mm. Bausch and Lomb objective marked 10X 16mm. Original Eyepiece is marked Bausch and Lomb, and has a ‘1’ marked on it.
