Suurennuslinsin

Suurennuslinsin, commonly translated as magnifying glass, is a convex lens that is used to produce a magnified image of an object. It is a simple optical instrument consisting of a single lens, typically mounted in a frame with a handle. The lens is shaped so that light rays from an object passing through it converge, creating a larger, virtual image that is perceived by the viewer. The degree of magnification depends on the focal length of the lens and the distance between the lens and the object. Shorter focal lengths result in higher magnification.

Magnifying glasses have a wide range of applications. They are essential tools for tasks requiring close examination, such as reading small print, inspecting intricate details in artwork or jewelry, and examining specimens in biology or geology. In everyday life, they are used by hobbyists, craftspeople, and individuals with low vision. Historically, magnifying glasses played a significant role in scientific discovery, enabling early scientists to observe details invisible to the naked eye.

The principle behind a magnifying glass is based on optics. When an object is placed within the focal length of a convex lens, the lens refracts the light rays emanating from the object, causing them to diverge as they exit the lens. The eye perceives these diverging rays as if they originated from a larger, more distant object, thus creating a magnified virtual image. The magnification power is often expressed as a number, indicating how many times larger the image appears compared to the object viewed directly.
