I am indebted to Timo Mappes for his help in describing this interesting microscope. The comprehensive database of binoculars with their parameters and users opinions. 9015506- focusing movement is irregular and a bit stiff Carl Zeiss ausJena T 1:2.8 f 50- No. Some dust is visible inside, I am not sure about fungus presence Carl Zeiss Jena Tessar 2.8/50- No. This is another example of a very fine "Jug-Handle" style Carl Zeiss microscope. Offered as faulty for the following reasons: Carl Zeiss Jena DDR Tessar 2.8/50- No. Here are two Zeiss 1B stands of the same period: one was sold via an agency in Paris and thus had the name of the dealer in Paris on the wooden case. Four additional are achromatic, high NA and high magnification. Three are apparently older (possibly originally supplied with the instrument).
The condenser is an Abbe-type with an additional upper iris diaphragm. The binocular configuration of this microscope was quite common, as there are illustrations of them on this very stand dating from 1920, shortly before the jug-handle was discontinued. This style of binocular is a so-called "Bitumi", introduced in 1920. To compare postoperative visual symptoms and spectacle freedom after bilateral implantation of the AT LISA 809M (Carl Zeiss Meditec, Jena, Germany) versus the AcrySof ReSTOR SN6AD1 (Alcon Laboratories, Irvine, CA) multifocal intraocular lens (IOL). Later, c1922, a binocular/stereoscopic eyepiece was added to the instrument. Originally it was sold with a monocular eyepiece. Two eyepiece configurations come with this microscope. It has a rotating stage with X/Y mechanical movement, a three position nosepiece, a rack and pinion coarse focus adjust and a Bergen fine focus mechanism. The stand has an oval cutout for handling the instrument, which is the source of the nickname "jug-handle base".
This microscope is a black lacquered upright compound microscope on a horseshoe base. All parts were undoubtedly made by Zeiss however attested by the various "Carl Zeiss, Jena" logos on the stand, stage, and eyepiece. On this microscope you can see the B&L logo on the top of the fine adjustment block as well as the eyepiece-barrels. During that time B&L added its logo to the instruments it sold in the US.
