Meniskläätsed

Meniskläätsed, also known as meniscus lenses, are a type of concave lens. This means one or both of its surfaces are curved inward. The term "meniscus" refers to the crescent-like shape of the lens. Meniskläätsed are characterized by a specific radius of curvature on their front and back surfaces. The difference in these curvatures determines whether the lens is converging or diverging overall. A lens with a more strongly curved concave surface than its convex surface will act as a diverging lens, while the opposite will result in a converging lens. They are commonly used in optical instruments such as telescopes and cameras to correct for aberrations. Their design allows for the manipulation of light paths in a way that can improve image quality. The precise shape and material of a meniskläätsed are critical to its intended optical function.
