Now absorbed by Leica Microsystems, American Optical (AO) designs were extremely popular for many years in educational and clinical microscopy. AO was first to recognize the advantages of infinity optics, ingeniously designing the nosepiece to focus while the stage, arm, and head stayed fixed. The fixed stage was perfect for micromanipulation and various custom applications. Strangely, no current microscope manufacturers have adopted this design. The AO Series 10 Microstar was particularly popular, and the AO Cycloptic stereomicroscope, introduced in 1957, was the first to have a common main objective, a feature now used in all research stereomicroscopes.
