#Ernst leitz wetzlar microscope serial numbers 212 serial number
Signed on the body tube "Ernst Leitz | Wetzlar", and serial number "359331" made in 1941.
3 compensator plates: Glimmer 1/4 λ, Gips Rot I Ord and Berek. 6 oculars from which two to be used with a colar. 6 objectives (from which one for immersion in water and two for immersion in oil).
Focusable Bertrand lens with adjustable diaphragm. Analyzer fitted on a sliding shoe into the lower part of the body tube. Polarizer with adjustable diaphragm and swing out condenser lens. Circular rotating stage (14 cm diameter) with 360-degree scale and vernier. Main focus by rack and pinion and fine focusing knob on the limb. No large diameter oculars are present.Polarizing microscope (lacquered brass) with nickel and black enameled brass limb and tube and iron cast horseshoe base, in fitted mahogany case with accessories and key. There is a side fine adjustment which is calibrated.Īn engraved area on the right side of the limb above the fine focus has the inscription: '1 Jntervall=0,002 m/m.' This is the exact inscription, likely an error in the engraving, as in German the word interval is spelled 'Intevall.' The diameter of the opening of the optical tube is large, to accept unusually large diameter oculars, and is supplied with an adapter, made of black plastic, to accept the supplied standard diameter oculars. Coarse focusing is by diagonal rack and pinion. Small wrenches are supplied for this purpose (see below). Each objective is held in place by a spring-loaded '3-point objective-changing clutch.' Each objective can be individually centered in the individual objective adapters accepting the society thread. There is a window slot at the lower end of the nosepiece with a shutter which can be opened or closed via a small knob. It can be slid in or out of the optical path. The analyzer is calibrated over a 90 degree range, in 5 degree increments, and has a rotation brake. There are also two small knobs to adjust the centering of the Bertrand lens in the optical axis.

Hina rani ka dhamal video songs free download mp4. There is a separate iris diaphragm integrated in to the Bertrand assembly.
It can be focused by a diagonal rack and pinion. The Bertrand lens sits well above the analyzer. The entire condensor and polarizer assembly is lowered or raised by rack and pinion. The upper iris and flip-up condenser is on a second dovetail slider with its own brake and can also be slid out of the optical axis, independently. Above the polarizer are the optical components of the condenser with a top which can be flipped up or down for higher powers. It can be locked in the path with another brake. The polarizer assembly can slide in and out of the optical path on a dovetail. It has a brake for its rotation, and at its bottom end there is an iris diaphragm, the distance of which from the prism can be varied by sliding it up or down. The polarizer rotates through 360 degrees, graduated in 5 degree increments. These prices assume the lens is in excellent condition.īetter pictures of the camera and lens would help. Coated lenses and lenses with red dials are worth more than non-coated lenses or lenses with black dials. The lens could be worth US $200 - $400 depending on the version. If it has a red dial, it could be worth a little more. Value of the camera and lens depends a great deal on condition.ĭo you know if the camera is functioning properly? Is the lens fogged or scratched? A Leica IIF in working condition with excellent cosmetics might be worth US $200 - $300. The camera looks like a Leica IIF, but I can't be sure unless you provide the serial number which is on the top of the camera. I'm assuming the numbers around the shutter speed knob are black and not red 'red dial' bodies are worth a little more. If the lens has a red distance scale and is in really fine condition it might make 250 GBP. In good condition with no dents, scratches or significant brassing, and if the lens is clean and clear, maybe 200 GBP for the body and 150 GBP for the lens.
All black dial cameras are 1/500, as were earlier red dial cameras. Ernst Leitz Wetzlar Company Microscope Serial Numbers Serial Number Year m2 18 50 18 91 1854.
