Antique Microscope by C.Reichert Wien

No.21728

Circa 1899

 

Fine example of a high quality 19th Century microscope in a fitted wooden case, complete with 3 eyepiece lenses and 3 objective lenses. The microscope and base are made of polished brass. The eypiece tube is extendable and is the main focus. It adjusts using a rack and pinion system with two brass knobs either side of the tube. It also has a fine focus knob with a round dial at the back of the microscope.

 

The microscope has a triple revolving nose piece which allows for all three objective lenses to be fitted. It rotates around so you can select the appropriate magnification for what you wish to study. 

 

It has a circular stage with two slide clips. The slide clips are not fixed but slot into two holes in the platform. They work well and firmly grip a slide. It is a very good quality microscope and the whole stage itself is adjustable by the small brass knobs either side - they move the platform very finely left / right and backwards / forwards so as when you are viewing a slide you can adjust your field of vision without having to take your eye off the specimen. There is also another knob which tightens the friction on the stage and allows the whole stage to be swivelled. 

 

Below the stage are two further complex pieces of equipment. There is an aperture ring for condensing the light with a magnifying lens below this which I believe focuses the light. This whole piece of equipment moves up and down by a rack and pinion system below the stage. 

Below this there is another piece of equipment which swivels out. It is stamped "C.Reichert.Wein". It has an adjustable aperture ring with a lens in it which I believe could be a polarising lens. This also adjusts back an forwards on its staging by rolling a knob along a rack and pinion. 

Below these pieces there is also a large adjustable mirror for shining the light source towards the microscope. 

 

The whole microscope tilts backwards and there is a lever to adjust the friction and the amount of force needed. 

 

It is labelled on the back of the base and the front of the tube with the makers name, model and serial number ; "C.REICHERT. WIEN. 21728." The serial number dates it to around 1899. 

 

The microscope comes with 3 eyepiece lenses. The first is labelled "Compens. 4. Tubusl. 160m/m. C.Reichert Wien". The second is labelled "18. Tubusl. 160m/m. C.Reichert Wien". I believe the third lens is slightly later and is just marked "12.5X Comp.205.".

The microscope comes with 3 objective lenses. All three have their original brass lens cases and are all marked"C.Reichert". There is a No.7a and No.4b and also a 'Brennweite 8m/m'. 

 

The microscope appears to be in good working order and I have set it up and tested it with a few old slides. The pictures are clear and the microscope focuses well but I'm sure the lenses would probably benefit from a clean. The microscope is far from new so please don't expect the optics to be like a new microscope. 

 

It comes in its original fitted mahogany case with a sliding section at the top fitted for the various lenses. There is also a fitted box within the case with a sliding top for storing slides etc. It is a good quality box with a lovely brass carrying handle and it comes with its original working key and lock.

 

The microscope measures approximately 13" tall when not extended. The eyepiece tube is approximately 1 1/4" in diameter. The box is 15" high X 8"deep X 8" wide.

 

It is of considerable age and is in very good condition. It has been used and will have normal signs of wear so please don't expect it to be brand new. The lenses have small specks of dirt on and although in working order it is really being sold as a decorative collectors item rather than a scientific instrument. It has been cleaned and the brass lightly polished and it displays very nicely. The box is sturdy and has a lovely aged patina.

 

I have done my best to describe every element of really a rather complex microscope. The best description comes from the photos so please look at them all carefully and if you have any questions at all please ask.
