DESCRIPTION: The microscope sits on a horseshoe foot. This form of horseshoe, with rear extension, might be more properly termed 'Y'-shaped, but the 'horseshoe' designation has persisted. Coarse focus is by diagonal rack and pinion. The coarse adjustment knob has a smaller secondary knob on the left side for rapidly changing the coarse adjustment; this knob can be changed to fit on either side of the microscope.

Fine focus is via the The left fine focusing knob is graduated as the plate states, in 0.002 mm increments. Because of space limited on the plate by its retaining screw, the letters mm are on top of each other rather than next to each other as normally would be the case. The exact signature on the fine focus plate is: 3oh 3 Discography Torrent more. '1interv.'

0.002mm' (but the m's are on top of each other). It was offered with options of three different this example being equipped with the 'Large Mechanical Stage, No. Wondershare Mobilego Keygen Generator Mac on this page.

This instrument does bear the simple “C Zeiss Jena” engraving on the slide Stage. On the Stage top and to the left of the company name are also engraved the microscope production and the series (compound microscope) serial numbers too. Right: C Zeiss Jena company trade name engraved on Stage of microscope Nr. Based on information coming from Zeiss Oberkochen based on materials found in the Carl Zeiss Jena Archive, we see the first definitive chronicling of the earliest Zeiss microscopes. The article si accompanied by a table of serial numbers by year and type (Simple versus Compound) with a sampling of the dates of certain microscope model’s introduction. Carl Zeiss, Jena.

Initially building single lens. Basic microscope design. Many microscopes were sold in wooden boxes with serial numbers on them and finding a vintage microscope with the box enhances the value.

Shown to the right. The stage has vernier scale graduations in both X and Y axes. A third scale and vernier was added for recording the position of the movable 'check-piece' or slide holder, which secures the position of the left side of the slide. The right side slide holder also slides in the same groove. This allows the X and Y verniers to then be used as a 'finder' to locate a specific spot on the slide repeatedly.

This stage also has rotational motion, with a locking screw knob. The rotating stage also has two centering screws with milled knobs. There is also a small lever to lock the mechanical stage forward and backward motion, a feature especially useful when the stand is inclined or even horizontal.

Another stage, the 'Photomicrographic Stage' (also shown for comparison on the ) was also offered as an option; this stage had a different kind of adjustment which assumed gross positioning of the slide by hand, and then only a fine adjustment via controls to allow the object to be carefully positioned for photography. This stand could also be provided with a rotating, but otherwise plain vulcanite stage with stage clips. The has diagonal rack and pinion height adjustment. This example is equipped with the Abbe Swing-out Condenser, a plain condenser also being offered. The condenser apparatus currently on this microscope has only one iris diaphragm, below the condenser fitting. This iris can rotate, and via a small diagonal rack and pinion, be offset from center to allow variations in indirect illumination.

The iris and the optical component (condenser) can be swung out of the optical axis separately as desired. The fitting that holds the condenser then remains in place to accept other accessories as desired. The microscope has a graduated draw-tube which is graduated from 14 to 19 cm by 1 mm. There is no stop to hold it in fully extended, making substitution of the Bitumi binocular head simple. There is an extra wide main optical tube to facilitate photography. The stand is supported between a double upright from the foot, and the inclination is both adjustable and can be secured at any inclination via a locking levered screw controlled from the back of the stage. The gimballed substage mirror is double sided and planoconvex, extending down from the tailpiece; although gimballed, the distance of the mirror from the stage cannot be varied.
