Microscope slide : ウィキペディア英語版 | Microscope slide
A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is placed or secured ("mounted") on the slide, and then both are inserted together in the microscope for viewing. This arrangement allows several slide-mounted objects to be quickly inserted and removed from the microscope, labeled, transported, and stored in appropriate slide cases or folders. Microscope slides are often used together with a cover slip or cover glass, a smaller and thinner sheet of glass that is placed over the specimen. Slides are held in place on the microscope's stage by slide clips, slide clamps or a cross-table which is used to achieve precise, remote movement of the slide upon the microscope's stage (such as in an automated / computer operated system, or where touching the slide with fingers is inappropriate either due to the risk of contamination or lack of precision) ==History==
The origin of the concept was pieces of ivory or bone, containing specimens held between disks of transparent mica, that would ''slide'' into the gap between the stage and the objective.〔Adam, George. Essays on the microscope. 1798 ()〕 These "sliders" were popular in Victorian England until the Royal Microscopical Society introduced the standardized glass microscope slide.
