€40,00 EUR
Skip to product information
An intriguing piece of historical measurement technology: the Dr. B. Lange Berlin Photo-Element S 60. Identified in the supplied information as an early selenium photocell, also known as a Sperrschichtfotozelle, this sensor is mounted on a metal base with a ball joint.
The circular sensor head and rounded base give the piece a distinctive mechanical aesthetic. Its appearance recalls a futuristic vintage microphone or an unusual space-age device. The inscription “Photo-Element Dr. B. Lange S 60 Berlin” emphasizes its technical character.
The name Dr. Bruno Lange is historically associated with the development of the selenium photocell. The precise production date of this example has not been established.
Important: this is a standalone sensor accessory, not a complete light meter. The matching analog readout unit, such as a lux meter or galvanometer base station, is not included. Without that equipment, this item does not constitute a complete measuring system. Function has not been verified, and no measurement accuracy or calibration is guaranteed.
This example shows visible signs of use and age, including wear to the housing and exposed wire strands at the connection. Please examine the photographs carefully for its cosmetic condition and the components present. A distinctive collectible for enthusiasts of historical instruments and industrial design.
Dimensions: approximately 11.5 × 8 × 8 cm.
Weight: 245 g.
