SZ Stereo Microscope

The innovative SZ Stereo Microscope, the first in Japan to feature a zoom function, was released in 1961. The user could rotate a variable magnification ring while observing the specimen and the image field of vision and magnification would change continuously while remaining in focus. This was the first microscope to be given a Good Design Award (the G Mark).
In the early 1970s, this microscope started to be used at semiconductor plants for testing and assembly. The microscope color coating was subsequently changed to "ripple pearl." In 1989, Olympus launched a new generation of SZ stereo microscopes.
