Standardised lens mount for mounting on microscopes.
Lenses and all optics, including the micrography grid, are in good condition, free of scratches and looks clear. Includes the high quality Alfred Gauthier GmbH shutter mechanism (T, B, 1/125, 1/50, 1/25, 1/10, 1/5, 1/2, 1 second) produced in Calmbach, Germany. This photomicrographic camera has no marking (I haven’t seen one like this before) is a collector’s item with historic value some of the first microscopic scale prints and photos were shot with this kind of camera. Photo micrographic produced from 1932 by Leitz Wetzlar. With optical reducing system 1/3x, release and eye-piece screw-mount. Micro attachment with shutter and focusing for connecting camera to a microscope. Used as a MIFILMCA, camera with Leica housing, without a shutter, and without a viewfinder is attached. Also a ground-glass disk a case key one nickel-plated stage clip and an extra small lens for the swing-out arm on the condenser.Extremely rare and hardly known this is a camera and a special device from Leitz Wetzlar (from 1932) MIKAS (part of the MIFILMCA). There are two slides for the tube slit: a Glimmer 1/4 wave plate and a Gips Rot I. This box includes includes five objectives, each on its own centerable adaptor, and two "clock-key" wrenches for adjusting the centering. At first it appears to be an item sold separately from the microscope, but it has two tracks to slide into the main case. Nickel-plated brackets are attached inside to hold the objectives. The box is fitted, made of wood, covered with leather, and lined in red wool. One ocular (8X) is stored in a sliding tray.Ī smaller box holds objectives and accessories. It has a nickel-plated handle and hardware, and angled dovetailing. This instrument is accompanied by a standing wooden case for storage. Readings are taken by means of the body tube and stage graduated circles with verniers. The fork on the body tube is hinged to its collar around the tube and can be swung out of alignment with the bar in order to allow for independent rotation of the analysers in the body and substage. The body tube and substage illuminating illuminating apparatus are linked together by roller-tipped forks that meet a vertical bar.
The substage mirror is plano-concave and mounted on a slider attached to a independent swing-out arm. A small swing-out lens at the top is attached to a knob. The polarizer is an Ahrens prism mounted in a sleeve at the bottom. The substage illuminating apparatus is what is called the "two-iris-diaphragm type, model a." The condenser is made of 5 lenses. It is graduated around the circumference and has two verniers. The object stage is circular and rotating.
It serves as a socket for a top analyzer-i.e., a cap nicol prism-to sit in.Ģ) graduated circle with vernier for use with analyzer.ģ) an Amici-Bertrand lens in a centering mount with an iris diaphragm, attached to a slider.Ĥ) Tube analyzer of the anastigmatic type with a Ahrens prism.ĥ) Slot for inserting accessories such as selenite plate, quartz wedge, or compensator. (They are described in more detail below.) So that each objective does not need to be continuously recentered, the base of the body tube has the patented Leitz "objective clutch changer."īetween the ocular and objective on the body tube there are the following:ġ) Cap analyser support provided with an index line. as/is Leitz 512738 Polarizing Trinocular Microscope Head Leitz 307-143.004 100W Microscope. THIS ITEM COMES WITH WHAT YOU SEE IN THE PICTURES IF YOU DON’T SEE IT, YOU PROBABLY WON’T GET IT. This item came from a working environment. 1999 This item is USED but should work as intended. The objectives are each mounted on an adaptor with centering screws for use with this polarizing microscope. Ernst Leitz Wetzlar Ergolux Microscope Type 020-559.025. It takes a wide-diameter ocular with a large field of view. The body tube is nickel-plated and of wide diameter. One interval on the drum is equal to 0.001 mm. The fine focus is by a micrometer screw equipped with a divided drum for depth measurements. Above the joint is a curved arm that holds the both the fine focus and coarse focus knobs and carries a bracket to which is attached the unusual body tube. A nickel-plated lever is used to fix the desired angle. The upright is rectangular and has a joint for inclining the microscope. The base is blackened brass with a horseshoe-shape and beveled heel. Description This is a Leitz petrographic microscope, model SM, which features synchronic rotation of the nicol prisms above and below the stage as well as independent rotation of the polarizer and analyzer through 240 degrees.
