Positive Meniscus Lenses

Meniscus lens is a concave-convex lens, which has an outer convex surface and an inner concave surface. If the outward radius is greater than the inward radius, the lens has a positive focal length and can be used as a magnifying lens. YZSY Optics offers uncoated or IR2 AR coatings meniscus lenses. Germanium substrates are ideal for IR applications.
