Plano convex lenses have positive focal lengths, converge incident light, and from both real images (as might be focused in a piece of paper), and virtual images (as are seen through the lenses when they are used as magnifiers). They are widely used in telescopes, collimators, optical transceivers, magnifiers, radiometers and condensers. Our plano convex lens usually use the material as BK7, fused silica, and other optical glass.
