Product Details
Opticreate 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 optical lens has a positive focal length and acts as a magnifier. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly.
Opticreate are the leading optics lens supplier for Meniscus Lenses, We has been exported to all over the world.
