HAND LENSES Meaning and
Definition
-
Hand lenses, also known as magnifying glasses or magnifiers, are handheld optical devices used to visually enhance the size or detail of small objects. They consist of a single convex lens held by a handle, allowing it to be easily held and manipulated by hand.
With a typical magnification power ranging from 5x to 20x, hand lenses provide close-up views of objects that are normally difficult to see with the naked eye. They are frequently used in various fields such as biology, geology, botany, and entomology, as well as in everyday tasks like reading fine print or examining small objects.
Hand lenses are often compact and portable, making them convenient for use in the field or on the go. They are designed for simple and effective magnification, requiring only proper positioning and focusing on the object of interest.
These lenses work on the principle of allowing light to pass through the curved surface, bending the light rays and increasing the apparent size of the object. The magnifying power of the lens depends on the curvature of the lens surface, as well as the distance between the lens and the object being observed.
Overall, hand lenses are valuable tools for visual inspection, providing a quick and accessible method for magnifying small objects and details.

Etymology of HAND LENSES
The word "hand lenses" is a compound noun formed by combining "hand" and "lenses".
The term "hand" originates from the Old English word "hand" which is derived from the Proto-Germanic word "handuz". This word is also seen in Old Norse as "hönd", Dutch as "hand", and German as "Hand". The origin of this word is uncertain, but it is believed to have ancient Indo-European roots.
The word "lenses" is derived from the Latin "lens", which means "lentil" or "lentil-shaped". It was first used in English in the late 17th century to refer to a transparent optical device that focuses or disperses light. The Latin word "lens" itself comes from the Proto-Indo-European root "lei-", meaning "to pour" or "to flow".
