History of the Röntgen Xebec 5cm F1.5 Lens
The Röntgen Xebec 5cm F1.5 lens was attached to the following X-ray camera set.
NIPPON-KOKEN's Indirect X-ray Camera Set
This X-ray camera set was manufactured by NIPPON-KOKEN. NIPPON-KOKEN was established in April 1943 in Tokyo to manufacture X-ray equipment.
Tatsuo Hori's novel "Kaze Tachinu" published in 1938 is a sad story that the fictional heroin dies of tuberculosis. At that time in Japan there were many people who died of tuberculosis.

NIPPON-KOKEN's Indirect X-ray Camera
Direct shooting of X-ray required huge equipment and darkroom. To solve this problem, a method of fluorescent image photographing by an X-ray indirect imaging apparatus was established.
In 1942, the Ministry of Health and Welfare of Japan established a fluorescent screen size of 35 cm x 35 cm as a standard. The screen size of the X-ray camera film was 24 mm x 24 mm. It was possible to take 50 pictures with one film magazine.
