Applications

American Optical stereo microscopes were widely used in electronics assembly, biological specimen examination, gemology, quality control, and light industrial inspection throughout the mid-to-late 20th century. The AO 571 head mounts onto compatible American Optical stereo microscope bases and stands, completing a stereo viewing system used in labs, universities, and inspection environments. American Optical (later Spencer and ultimately absorbed into Reichert Technologies) produced a long line of high-quality stereo microscopes that remain popular among technicians, hobbyists, and lab operators who need reliable, serviceable optics at a reasonable cost. Replacement heads, eyepieces, and objectives for AO stereo microscopes continue to be sought for maintaining or upgrading existing AO stands still in service.
