A simple magnifying glass consists of a convex lens of a small focal length.
A simple magnifier is a converging lens and produces a magnified virtual image of an object located within the lens’s focal length. Magnifying glasses are typically used at a larger distance from the eye, are larger and typically have a longer focal length of 125 mm or more. The magnification of a loupe is defined as the parent object sizes ratio as observed with and without the glasses.
