Hand lens
A hand lens is nothing more than a hand-held magnifying glass. The term "hand lens" is used primarily in a laboratory setting. The lens, or glass, is set into a frame with a handle attached. The fictional Sherlock Holmes popularized the hand lens, or magnifyng glass when looking for clues to solve a mystery.
The mass of a hand lens can vary depending on the size and material it is made of. Typically, a hand lens can weigh anywhere from a few ounces to a pound.
The main parts of a hand lens include the lens itself, the frame or housing that holds the lens, the handle for holding and maneuvering the lens, and sometimes a protective cover or case.
