            The Plano Convex lenses are made from Sapphire material, which are manufactured with one concave surface and one plane surface. These lenses have negative focal lengths. These lenses diverge collimated incident light. They form virtual images which are seen through the lens. They are often used to expand light or to increase focal lengths in existing systems. We also offer precision grade plano Convex lens with tighter manufacturing tolerances.
