Meniscus Lens Definition
Meniscus lenses-with their distinctive convex-concave design-excel at minimizing spherical aberration while controlling light convergence or divergence. Positive meniscus lens glasses focus parallel light into tight spots (convex side toward the source) or, when paired with other meniscus optics, shorten focal lengths to boost numerical aperture (NA). Conversely, negative meniscus lenses (thinner at the center) diverge light and are often combined with other lenses to lengthen focal distances and reduce NA. Ideal for precision systems requiring aberration correction and tailored light manipulation.
Overview of Menicus lens
ATOPTIK's double meniscus lens is a high-performance optical component with an asymmetric concave-convex structure. Its unique shape offers excellent performance in reducing aberrations, enhancing beam quality, minimizing spherical aberration, and controlling beam divergence. Minus meniscus lens and plus meniscus lens are commonly used in applications such as beam collimation, optical imaging, laser beam expansion, fiber coupling, and sensors.
