Super Photo universal research microscope with a photographic system
For researchers, recording results of observations through a microscope was a vital issue. In the prewar period, a drawing attachment was used to sketch the observed specimen by hand. The marketing of a drawing prism, the Abbe Drawing Attachment, began around 1934.
At the same time, attempts were made to use photography to preserve observation records. Around 1925, Olympus released the Olympus Microphotograph Apparatus PMA and PMB (horizontal optical axis) for microscopes and Olympus Microphoto (56x93mm), a compact photographic device for microscopes the size of a business card. These technologies were then used in the designs for subsequent photographic devices (such as the PM I, PM II, and PM III).
The Super Photo universal research microscope with a photographic system, introduced in 1938, was the most advanced microscope of the prewar period. Designed for biological and industrial applications, the model had a host of accessories for bright/dark field, neopak, and projection purposes.
