XA Binocular Stereo Microscope

The first stereo microscope from Olympus was the Binocular Stereo Microscope XA, launched in 1933. This microscope used a Greenough Optical Design.
At the time of launch, stereo microscopes were commonly used for microdissection. The Olympus microscope was designed for ease of use, featuring a hand rest on both sides of the stage. There were three objective lenses and the microscope had a maximum total magnification of 48x. Olympus then launched the XB and XC models before the Second World War.
