Microscope slide

A microscope slide is a thin sheet of glass used to hold objects for examination under a microscope. A standard microscope slide (shown on the right) is 75 x 25 mm (3" X 1") and 1.2 mm thick. A range of other sizes is available for various special purposes.

Graticule slide

The text above describes a standard microscope slide. However, there are many special purpose slides. For example, a graticule slide is a microscope slide that is marked with a grid of lines (for example, a 1 mm grid) that allow the size of objects seen under magnification to be easily estimated. Such grids are perhaps more often employed in counting exercises.
