Spherical Lens

Spherical lenses are the most common lens type and offers many standard versions, including Bi-convex (positive lens), Bi-concave (negative lens), Plano-concave, and Plano-convex in Fused Silica either AR coated or uncoated for your needs. Other varieties, such as meniscus, are available on a custom basis and we offer other substrate materials as well.
