Magnifiers

A magnifying glass is a magnifying glass, which is usually attached to a handle or a device for setting up. The so-called burning lens - a convex converging lens - usually has a magnification of 2 to 15 times. Loupes are generally used for viewing very small things, which you can not recognize properly with normal vision. The reading magnifier is the most common form. It has a fairly large lens with handle and up to 6x magnification. Loupes for watchmakers or jewelers are detail magnifiers, which have a rather small field of view and a small lens diameter, but up to a 15x magnification.
