Loupe

A loupe ( ) is a simple, small magnification device used to see small details more closely. They generally have higher magnification than a magnifying glass, and are designed to be held or worn close to the eye. A loupe does not have an attached handle, and its focusinglens(es) are contained in an opaquecylinder or cone. On some loupes this cylinder folds into an enclosing housing that protects the lenses when not in use.
