Magnifying glasses are tools that are used to observe objects closely. These glasses magnify the size of the object, making it appear larger than its actual size. They are widely used for various purposes in different fields, including science, medicine, jewelry-making, and exploration.

Working Principle

The working principle of magnifying glasses is simple. They use a convex lens to refract light rays, which converge at a focal point. When an object is placed between the lens and the focal point, the lens magnifies the image of the object, making it appear larger and more detailed.

Loupe magnifying glasses – these are small, high-powered magnifying glasses that are used for detailed observation, such as in jewelry-making, watch repair, and scientific research.
Headband magnifying glasses – these are worn on the head like a headband and are used for hands-free observation, such as in medical examinations and surgeries.
Stand magnifying glasses – these are large magnifying glasses that are mounted on a stand or a base. They are commonly used in classrooms and laboratories for group observation.
