Then the pillar, (with the foot folded on top of it), is thenДЇolded backward on the inclination joint. The mirror stem then is raised up parallel with the body To fold up the microscope for storage, first the tube and draw tube are In my example, I do note slight image shift when using the fine focus. Moderate power it always lacked an oil immersion high power objective. To prevent tipping the scope right or left.

With the low power objective attached and the footДЄnd pillar as a handle, it could also be used as a handheld microscope Another way to use this microscope is as aДemonstration microscope, with a slide on the stage, using the foldedДЇoot as a handle. Placed on the foot, illumination would be by holding the instrument up For low power views of transparent objects Stage with the stage clips moved to the foot, which has holes toДЄccommodate the stage clips. Used for low power views of slides, using the foot as an accessory Special low power objective which, after removal of the condenser,ДЄllows inspection of a solid surface through the foot it can also be The objective assembly can be exchanged for a Higher power achieved by turning the knurled knob to bring an extraД«ottom lens into place. The main objective assembly provides two powers with the Coarse focus is by push-pull and fine is by a knurled ring justДЄbove the arm which moves the sleeve holding the main tube.

Swiveling substage mirror which is concave and can be brought around to It arises from a horseshoe foot to an inclination joint. It is signed 'Ernst Leitz, Wetzlar, N o 286794'.
