A very unusual and most interesting early piece of Nautical optics. This is an original vintage 1880s or so ZEISS NIGHT MARINE GLASS. This is a hand held 7 1/2 power spy scope that has special construction for night viewing at sea. The body appears to be brass wrapped in leather. All lenses are present and the instrument is in fine condition overall. It is stamped on the viewing end panel

ZEISS NIGHT MARINE GLASS 7 1/2 POWER BAUSCH & LOMB CO ROCHESTER NEW YORK

I could find nothing on this device despite conducting an intensive and exhaustive search on the net. The scope is 4" long x 2 1/2" wide and 2" fat. I have never seen anything like it. If you have then please clue me in.

is some information about the ZEISS Company copied from the internet with thanks to the publishers. Please note that the section wehre ZEISS joins forces with BAUSCH AND LOMB is highlighted at bottom:

Carl Zeiss - A History Of A Most Respected Name In Optics.

From its inception through to the middle 19th century, lens making was a craft that was essentially passed on from generation to generation. Innovations had typically resulted from trial and error experimentation; this was a costly and time consuming process that could not factor in all of the possible variables in lens making materials and design. It would be left up to one who could employ scientific methods of study, and then devise the mathematical formulas to characterize the physics of optics to make the next important technological leaps possible. It would then be asked of a chemist to invent and manufacture those raw materials necessary to make the new designs possible. And it would be one man to bring this combination together to create a concern of unrivaled accomplishment.

Carl Friedrich Zeiss (b. 11 September 1816 in Weimar - d. 3 December 1888 in Jena) grew up apprenticed in the shop of Dr. Friedrich Ksrner, becoming well familiar with the operation of fine tools and machinery to make microscopes and scientific instruments. Ksrner was a machinist who provided such instruments to the German court. Zeiss attended lectures at the University of Jena w he studied mathematics, physics, anthropology, mineralogy, and optics. He traveled as a journeyman for some years and completed his practicals at the Physiological Institute in Jena under Professor Schleiden. On 10 May 1846 Carl Zeiss submitted the required application to the Weimar authority requesting permission to open a mechanical workshop. After this was approved Carl Zeiss opened on 17 November 1846 at Neugasse 7, Jena on the Saale River in the district of Thuringia in Germany for the production of simple microscopes, measuring instruments, and other precise optical and mechanical instruments. In the first year of operation he sold twenty-three microscopes, not bad considering the state of the economy and his not being well known at the time.

In September 1847 Zeiss moved to a larger facility at Wagnergasse 32 and hired his first apprentice. Among his customers was the University of Jena for whom he made and repairs scientific equipment. Zeiss began to make improvements in microscopes, offering simple microscopes and in 1857 introducing the first compound microscope (employing an objective and an eyepiece), the "Stand I". In 1861 Zeiss compound microscopes are declared to be "among the most excellent instruments made in Germany" and he is awarded a Gold medal at the Thuringian Industrial Exhibition. By 1864 the need to house some 200 employees results in another move of the workshop to a third larger site at Johannisplatz 10. In 1866 the 1000th microscope is delivered; the Carl Zeiss shop is recognized throughout European scientific circles for the quality of its microscopes. Carl Zeiss original workshop has been restored and remains a subject of attention to visitors to Jena today.

Up to this time advances in optical designs and materials relied heavily on inefficient trail and error efforts. Realizing that the improvement of optical instruments demanded advances i...
