Meniscus lenses Product
Meniscus lenses are convex-concave lenses. They have one outward curved face and one inward-curved face. If the outward curve is sharper than the inward curve, the lens has a positive focal length and acts as a magnifier.
We can manufacture lenses in any optical material required. Please contact us with your specific requirements.
