Mizuho GHA
The Shori microscope launched in 1920 was designed with an easily portable arm shape. The Mizuho GHA, launched in 1925, featured the same arm shape and had a square stage. It was a general-purpose microscope that could be used for bacteriological examinations and other applications.
In October 1929, the Wall Street crash triggered a global financial crisis. Against a backdrop of an ongoing global depression, the company won a major order for 600 microscopes from the Osaka Dental and Medical Technical College. This order not only improved the company's business prospects considerably, it also made a significant contribution to further advances in microscope technology.
