Zoom binoculars - 1850-1900 - Germany - Jacob Sachs-Hof Optiker

Presented is a particularly well-preserved theater glass from the German optician Jacob Sachs, Cologne and Berlin.
Jacob Sachs (also often written Jakob Sachs) was a well-known German court optician who produced high-quality optical instruments in the late 19th and early 20th centuries.
He was also appointed court optician!
The title “Hofoptiker” (or Hof-Optiker) was a predicate title. It meant that Jacob Sachs was an official supplier to a princely, ducal, or royal house (often the Prussian or a regional Rhineland noble house). This title stood for the highest craftsmanship, excellent glass quality, and fine mechanics, which is why his pieces are still popular with collectors today.
Antique pieces from his workshop are today popular collector’s items in the category Vintage Optics and Arts and Crafts.
