Fuji

The company also launched the Fuji microscope in 1920, featuring a built-in coarse motion mechanism. The inclusion of both fine and coarse motion mechanisms allowed for easier focusing. Moreover, the Fuji used an Abbe condenser in its illumination optics.
The company started factory operations in 1920 with the following line-up: Asahi (medical, sericulture applications), Homare (sericulture, primary/junior high school applications), Yamato A (medical, sericulture applications), Yamato B (medical, sericulture applications), Fuji (specialist medical applications), Heiwa (specialist medical applications), and Shori (specialist medical applications).
There was demand for high-quality microscopes from the textile industry, Japan's core industry at the time, to research and test for silkworm diseases, such as pebrine.
