Collection Screen Savers Win Wallpaper Mac Wallpaper Movie Gallery Benjamin Martin Solar Microscope Prolific British instrument designer Benjamin Martin made a wide variety of microscopes including the solar microscope illustrated below. The microscope is designed to fit into an opening in a window shutter and is used to project a large image on a screen, enabling several investigators to simultaneously examine specimens at high magnification.
Sunlight is employed to illuminate the specimen and provide image- forming light rays.
The body tube is constructed of cardboard covered with green shark-skin and contains a condenser lens at the base. A brass drawtube contains a Wilson-style microscope depicted here with a specimen slide fitted into the spring stage. A metal slider containing three objectives fits over the eyepiece to enable the microscopist to change magnification. Focus is achieved with a rack and pinion controlled by a knurled knob.
