To be specific DDR Carl Zeiss Jena multi-coated Jenoptem 8x30w binos.Your Jenoptem is a Deltrintem model, which was built under that name from 1920 to 1990.Note that there was a thriving business making Zeiss 7x50 replicas, but nobody built fake Zeiss 8x30s, to my knowledge.
Carl Zeiss Microscope S Serial Number ConceptWith the information from that means they were produced between 1928-1929 if I understand the serial number concept.
If I have read the serial number info wrong can someone please point me in the right direction as to dating these. Ernst Leitz of Germany and Parisian Camille Sebastien Nachet made quality microscopes that survive to this day; Watson Son began operations in mid-1800s England; Powell Lealand, Beck, and Aransberg are other names associated with the collection of antique microscopes. A bridge to an age when craftsmanship was as important as functionality, a vintage microscope is a work of art as well as science. The First Microscopes In the late 16th century several Dutch lens makers designed devices that magnified objects, but in 1609 Galileo Galilei perfected the first device known as a microscope. His invention, a compound microscope, had a convex and a concave lens. ![]() These first fledgling microscopes were generally built and used by a scientist. They can only be found in museums and are not available to the average antique microscope collector. Usually made of brass, the first microscopes were monocular instruments with simple lenses. ![]() Carl Zeiss Microscope S Free To FollowFor further history reading feel free to follow our link on the History of the Microscope. Zeiss Microscopes The German lens maker, Carl Zeiss, excelled at crafting precision lenses and began manufacturing microscopes in 1847. Initially building single lens instruments, in 1857 his firm began designing compound microscopes. Made of brass, many of these instruments had a black japanned base. His later microscopes used a draw-tube coarse focus and a knob controlled fine focus. He further refined the instrument with the incorporation of a rack and pinion coarse focus and fine focus enabled by a graduated wheel. Considered the finest optical instruments of the time, different magnifications were obtained by inserting eyepieces of varying lens strength into the monocular head in combination with different objectives. Bausch Lomb Immigrating to the United States from Germany in middle of the 19th century, Jacob Bausch and Henry Lomb began their association by manufacturing eyeglasses. Initially manufacturing single lens microscopes, they graduated to producing compound microscopes in 1874. They used different methods for focusing the instrument: a crew thread focus control on the nose end of the barrel, later discontinued in 1878, a draw tube similar to several other manufacturers and a rack and pinion system. Carl Zeiss Microscope S Professional Model ToweringManufactured in 1876, the first professional model towering 17 tall was the Bausch Lomb Model 76. Mainly constructed of brass, this model had nickel plating and hard rubber mounts for the eyepieces. A frictionless fine focus was achieved by using a micrometer screw located at the rear of the tube. Redesigned as a binocular microscope in 1883, it was one of the first commonly used binocular scopes. Originally selling for 200, this model is a fine collectible today. ![]()
