Introduction of Meniscus Lenses


One side of meniscus lens is convex, another side is concave. It can be a convergent lens or a divergent lens, which is decided together by refractive index, curvature and radius. The two surfaces of meniscus lenses are in the same direction. Meniscus lenses correct aberrations, eliminate chromatic aberrations and change spherical aberrations. They often combined with other lenses to form an optical system, changing the focal length of extra lenses. Widely used in corrective lenses, condensers for lighting systems, CO2 lasers and infrared optical systems. If the outer arc of the meniscus lens is greater than the inner arc, it can be used as a magnifying glass.

Meniscus Lenses


Spherical lens processing types


Plano-convex lenses, double-convex lenses, plano-concave lenses, double-concave lenses, positive meniscus lenses, negative meniscus lenses, flat lenses, single-cap lenses, double-convex double-step lenses


Meniscus Lenses


The meniscus lens can reduce small spherical aberration and can produce the smallest focus of collimated incident light, depending on the relative curvature of the two surfaces, the meniscus lens can be a positive lens or a negative lens. The center of the negative meniscus lens is thinner than the periphery, while the center of the positive meniscus lens is thicker than the periphery.
