Details:

The sub stage Darkfield condenser is hinged at the back end. Because the condenser is of Darkfield type, and permanently mounted aligned. I have found FedEx is the most reliable shipper of these delicate instruments. Darkfield microscopy requires patience and the use of immersion oil; both objective Lens condenser are oiled to slide careful focusing is critical, in order view specimen avoid damage microscope.

I have tested this microscope and it provides excellent Darkfield images. Let's have a closer examination of this instrument: The eyepiece is 10X Huygens. The objective Lens is a fine Busch and Limb iris diaphragm objective, 97X. The bulb is brand new.

My are written by myself and based upon my knowledge of, and/or experience with, the item I am offering for sale. The iris operates smoothly and positively. As stated, all bright parts are rhodium plated. All bright parts of the microscope are rhodium plated note: they NOT chromium.

Darkfield illumination can be compared to the effect produced when a beam of sunlight illuminates particles dust floating in air. I ship my microscope by FedEx. These microscopes were used in laboratories and hospitals for the examination of blood smears rapid identification spirochetes Tropism palladium. You can see photos of the pages this brochure in last few listing.

A Darkfield microscope requires the use of immersion oil. The fine focus knob is calibrated such that each 2 divisions on the scale correspond to a movement of 5 microns. Rhodium is a rare coating worth more than gold and virtually guaranteeing permanent brightness without corrosion. The mechanical stage is clean and works smoothly in both the X Y- directions.

The serial number of this microscope, 151187, places its date manufacture in the year 1938, or just at start WWII. Slides are held firmly in place by the clamping mechanism. It is a beautiful instrument. Organisms become luminous against a dark background and the views can be striking.

The objective Lens can be used for either Darkfield or bright field microscopy, however in mode as use on this microscope the iris diaphragm of is closed down somewhat to establish compatibility with condenser. The only manipulation necessary is focusing the objective. Similar to the night sky with bright stars against a black. Coarse and fine focus knobs operate smoothly are rhodium plated.

The sub stage condenser is permanently aligned with the optical path and objective Lens. For cleaning, the knurled screw at front of condenser is unscrewed which allows lowering for easy cleaning. Some microorganisms are nearly invisible when using a normal bright field microscope, but with Darkfield microscope they become luminous. The condenser is of the Darkfield type, permanently mounted on a hinged mount and aligned.
