A hand magnifier is a portable, handheld optical instrument that uses a convex lens to produce a magnified image of an object. It is commonly used for inspection, reading small text, or examining fine details in a variety of fields like electronics, jewelry, biology, and more.
Main Parts:
-
Lens: The main component, usually made of glass or acrylic, with a convex shape to enlarge objects.
-
Handle: Attached to the lens frame, allowing easy grip and movement.
-
Frame: Holds the lens in place securely.
Working Principle:
When you hold the magnifier at a proper distance from an object, the convex lens bends light rays to form a virtual, upright, and magnified image. The image appears larger and clearer to the human eye.
Common Uses:
-
Reading small print (books, labels, prescriptions)
-
Inspecting circuit boards or electronic components
-
Studying insects, plants, or specimens in biology
-
Detecting flaws in jewelry or watchmaking
-
Forensic and detective work (think Sherlock Holmes!)
Types (Based on Design):
-
Simple hand magnifier (basic lens with handle)
-
Illuminated magnifier (has built-in light source for better visibility)
-
Folding magnifier (compact, foldable design for portability)
