hkItem Name : Extremely Very Nikon Model H Field Microscope
Serial no. : 38650
Reference : The circa-1960s Model H field microscope was a laboratory-grade diagnostic instrument that found its way into the hands of physicians around the world,finished in chrome, black enamel, and leather, and like a fine camera, can be handheld, mounted on a tripod, or carried by a neck strap. A reinforced leather case safely stores the microscope, accessories, and an immersion oil dispenser, though it is not illustrated here. The Model H weighs about 800 grams and its design incorporates a high eyepoint, widefield, compensating eyepiece, a battery-powered illuminator, an Abbe condenser, and a fine focus wheel. For observation, specimens are mounted facedown under the clips on the crosswise traveling stage.The optical path of the Model H, which is actually an inverted microscope, features a long-base prism typical of the circa-1930s John N. McArthur design for portable instruments. The objective changer knob provides the instrument's operator with a choice of three of the ten available parfocal, achromatic objectives that range in magnification from 4x to 100x. Six of the lenses are designed for brightfield/darkfield microscopy, while the other four are for phase contrast imaging. A special port on the side of the microscope allows the introduction of immersion oil when the 100x oil objective is engaged, and beneath the black body there is a diaphragm control and filter slot.
