Meniscus Lens

Meniscus lenses—also known as concave-convex lenses—are fundamental precision optical components defined by a distinct convex outer surface and a concave inner surface. A key optical characteristic of meniscus lenses is that when the curvature of the convex outer surface surpasses that of the concave inner surface, the lens achieves a stable positive focal length, making it a core choice for magnification applications. This positive focal length property is what makes meniscus lenses the go-to optical element for basic and precision magnification needs in various simple and professional optical setups.

As a classic concave-convex lens type, positive focal length meniscus lenses are widely used in daily and industrial magnification scenarios, from common handheld magnifiers to entry-level optical imaging systems. Their unique curved surface structure not only ensures reliable magnification performance but also features simple light beam control capabilities, making them easy to integrate into basic optical assemblies. Unlike complex multi-element lenses, meniscus lenses offer a cost-effective solution for magnification requirements while maintaining basic optical stability.

AOS Optics supplies high-performance standard and custom meniscus lenses to match diverse optical application needs. Our concave-convex lenses are crafted from premium optical materials including H-K9L optical glass and fused silica, with optional anti-reflection (AR) coatings for visible and near-infrared spectral bands to enhance light transmittance and magnification clarity. We support tailored adjustments for curvature parameters and substrate materials, ensuring our meniscus lenses perfectly fit your specific magnification or optical system integration requirements.
