Meniscus lens element

Negative meniscus lens is thicker at the edges than at the center. These lenses combine both concave and convex surfaces with overall negative focal length (light (laser) diverges). Alien Photonics negative meniscus lens has one surface that is concave (curving inwards) and another that is convex (curving outwards). This makes them thinner at the center and thicker at the edges, while also resulting in negative focal length. This specific shape is used to diverge light (e.g. laser beam). Negative meniscus lenses play a crucial role in diverse optical applications where their unique ability to diverge light, correct specific aberrations, and improve system performance is required. They are very helpful in designing optical systems that demand precise control over light propagation, ensuring optimal performance across a broad range of technologies and devices. Negative Meniscus Lens for diverging light (laser) rays The primary optical function of a negative meniscus lens is to diverge light rays that pass through it. This is useful in applications that require the spreading of light, such as in certain types of optical testing equipment, beam expanders, or in systems designed to reduce the intensity of a focused laser beam. Improving image quality with Negative Meniscus Lenses When used in combination with other optical elements, negative meniscus lenses can help to improve the overall image quality. That is done by balancing out converging effects of other lenses, particularly in complex lens systems where control over the light path is crucial.
