With the low power objective attached and the foot and pillar as a handle, it could also be used as a handheld microscope to observe stationary subjects, as shown in the illustration on the front page of a which can be seen at the bottom of this web page. Another way to use this microscope is as a demonstration microscope, with a slide on the stage, using the folded foot as a handle. This objective assembly can be exchanged for a special low power objective which, after removal of the condenser, allows inspection of a solid surface through the foot it can also be used for low power views of slides, using the foot as an accessory stage with the stage clips moved to the foot, which has holes to accommodate the stage clips.įor low power views of transparent objects placed on the foot, illumination would be by holding the instrument up towards a light source. The main objective assembly provides two powers with the higher power achieved by turning the knurled knob to bring an extra bottom lens into place. Coarse focus is by push-pull and fine is by a knurled ring just above the arm which moves the sleeve holding the main tube. The condenser is threaded to screw into the the hole in the stage. Under the stage is a miniature detachable Abbe condenser with iris diaphragm and clips to accommodate a substage filter. There is a swiveling substage mirror which is concave and can be brought around to the top of the stage for illumination of opaque objects. It arises from a horseshoe foot to an inclination joint.
