Wallpaper Mac Wallpaper Movie Gallery Bertrand Box Microscope Meticulously crafted in Paris, France, the miniature Bertrand drum microscope is accompanied by a beautiful mahogany box and dates back to about 1841. The mahogany storage box is an integral part of the microscope and is designed to serve as a base that anchors the barrel-shaped instrument.
Fine focus is achieved by sliding the body tube closer to or farther away from the specimen.
The mechanism for fine adjustment is composed of a steel spring clamp positioned above the cylinder assembly and is manipulated by turning a milled-head screw. Focusing is further enhanced by a choice of three interchangeable objectives of varying magnification. The specimen stage of the compound monocular microscope is composed a single fixed plate.
