Blendux Type I
Blendux Type II
Gossen Blendux exposure meter
The Blendux exposure meter was introduced in 1933 after the Photolux and the Ombrux , Paul Gossen's first
exposure meters. The Photolux / Ombrux was introduced at the fair of
Leipzig in 1933. It was the first photo electric exposure meter build by
Paul Gossen. The Photolux, very shortly after introduction, was renamed to Ombrux
and was made for photography while his
counterpart the Blendux was made for movie (cine) purposes.
The measuring element is a selenium photovoltaic cell and the big glass lens on
the front was taken from a flashlight (electric torch) manufactured in that time in
Germany. The meter is accompanied by 2 aluminum plates holding tables
and information about use frames/second, aperture and film types. The
short form users guide is printed on a aluminum plate inside the case and on the
back of the meter. The Blendux Type I was for the German market. The
Blendux Type II is an export model for the international market.
