Meniscus Lenses are also called Concave-convex Lenses. The lens has an external convex surface and an internal concave surface. If the radians outward are greater than the radians inward, the lens has a regular focal length and is used as a magnifying glass.

AOS provides meniscus lenses without coating or anti-reflection coating to meet your different applications in various bands. Anti-reflection coating includes UV, VIS, NIR, and SWIR, which are double-sided coatings that can greatly reduce light reflection on the surface of the component and increase the transmittance of the concave-convex lens.

AOS Optics customizes meniscus lens of a variety of materials. Among them, H-K9L optical glass substrates are suitable for visible light and near-infrared band applications, germanium, silicon, zinc selenide, calcium fluoride and other substrates are suitable for infrared band applications, and fused silica is suitable for Used in UV band applications.
