Left the company and formed their own firm. Kellner'sĬousin and assistant, Ludwig Engelbert took over the company briefly.īy December 1856, Friedrich Belthle another company workman took overĪfter marrying Kellner's widow. Unfortunately he died of tuberculosis in 1855 at a young age.
As his fame spread, his business increased. HISTORY: Carl Kellner founded the Optical Institute of Wetzlar aboutġ849 with Moritz Hensholdt and became famous for his OrthoscopicĮyepieces for both the telescope and microscope. All other mechanical parts work flawlessly. With the latter problem, it is possible to use the coarse focus, albeit Stripped, and no longer holds the pinion box cover on tightly. The small brass screws holding on the pinion box cover is apparently Mechanically it is in good condition, exceptįor some loosening of the pinion box.

I should also note a thin horizontal crack in the supporting pillar, but no apparent repair to it, the screws attaching it to the bottom plate apparently holding it together quite tightly. Ring portion of this support retains its original lacquer. The most obvious loss on the upright portion of the main support the The lacquer is all original, with a few minor losses, with Realistically repainted to, as much as possible, resemble the originalįinishes. Severe damage to the finish of the stage and foot. NOTE ON CONDITION AND OPTICS: This microscope came to me with Is held on by two narrow pieces of spring steel from under the stage,Įach held in place by a single tiny screw. The stage center is round and has a knurled edge and can be rotated. The fine focus of that pillar is from under the stage with the knurled fine focus knob. Coarse focus is via a single knurled knob acting via straight rack and pinion to the round continental limb. there is no provision for substituting a condenser. This wheel of apertures, or 'stops' is permanentlyĪttached i.e. The back edge of this triangle, the side with the rack, is actually rounded in shape. Of the apertures from the stage and the fact that the rack is nearly triangular and runs through the stage itself rather than being on a tail piece. An unusual feature of this is the rack and pinion control of the distance The substage includes a conical wheel of apertures, including one slit for oblique illumination. A swinging tailpiece supports a small single-sided concave mirror.
