What Is a Meniscus Lens?
A meniscus lens is an optical lens characterized by differing refractive indices between its central and peripheral regions.
Available in concave or convex shapes, the lens operates by allowing light to enter, refracting it, and then exiting the lens. Meniscus lenses are utilized across various fields such as cameras, telescopes, microscopes, and eyeglasses.
Cameras and telescopes are prized for their ability to magnify distant subjects, while eyeglasses, serve the purpose of vision correction.
The basic structure of a meniscus lens typically includes glass and a lens frame for protection. Although effective in refracting light and magnifying subjects, meniscus lenses may introduce distortion at the periphery. Additionally, they are susceptible to damage from impact and vibration, necessitating careful handling.
