American Optical AO Series 150 “One-Fifty” Microscope
Plan Achro Objectives
Vintage American Optical AO Series 150 “One-Fifty” binocular microscope, made in the USA. This precision laboratory instrument features 10x wide-field eyepieces (AO 138) and a rotating nosepiece with Plan Achro objectives: 10x/0.25, 45x/0.66, and 100x/1.25 oil (Cat. 1079). It includes a mechanical stage, coarse and fine focus controls, and built-in Philips 7387 6V 10W illumination. Constructed with AO’s hallmark gray enamel housing and heavy cast-metal frame, this model combines durability with clean optical performance.
This particular example was physician-owned, reflecting the professional standard to which the AO Series 150 was built. Widely used in clinical, research, and educational settings, the “One-Fifty” earned a reputation for reliability, optical precision, and ease of service. A fine example of American-made scientific craftsmanship, equally suitable for practical laboratory work or as a collectible display piece representing mid-century medical instrumentation.
Condition
