Description
A vintage Nikon Model H portable field microscope by Nippon Kogaku (now Nikon), serial number 42544, believed to have been made in the late 1960s. Resembling a classic rangefinder camera at first glance, the Model H was a laboratory-grade diagnostic instrument used by physicians around the world. It is based on the John McArthur design for portable microscopes, using a long prism light path in an inverted layout, so specimens are placed face down on the stage.
Fully tested and working. The battery-powered illuminator lights up with the slide switch on the underside (uses 2 AA batteries, not included). A hinged cover with a built-in mirror (approx. 2cm / 0.79in) reflects the lamp light, with an adjustable diaphragm and condenser lens below. The objective changer dial switches between objectives, and the focusing wheel under the center moves the objective up and down, with a cover that locks the focus when closed.
Test observations were made at 40x, 100x, and 400x using human placenta (H&E stain) and diatom slides (see photos), and all objectives are in good condition. The inside of the base was checked and is free from rust, and the battery compartment works properly. Comes with the original leather case.
