Microscope slide

A microscope slide was initially a 'slider' made of ivory or bone, containing specimens held between disks of apparent mica. These were popular in Victorian England until the Royal Microscopically Society introduced the uniform microscope slide in the form of a thin sheet of glass used to hold objects for examination under a microscope. A standard microscope slide is 75 x 25 mm and about 1.0 mm thick. A range of other sizes is obtainable for various special purposes.
