Bikonveksläätsed

Bikonveksläätsed, also known as biconvex lenses, are a type of lens that is convex on both sides. This means that both surfaces of the lens curve outwards. Bikonveksläätsed are thicker in the middle than at the edges. Because of their shape, they are converging lenses, meaning they cause parallel rays of light to converge at a focal point. The focal length of a bikonvekslääts is determined by the curvature of its surfaces and the refractive index of the material from which it is made. These lenses are commonly used in optical instruments such as magnifying glasses, telescopes, and cameras to magnify objects or form images. Their ability to converge light makes them essential components in systems requiring focused light beams. The precise shape and material properties of a bikonvekslääts can be engineered to achieve specific optical performance characteristics.
