Knight Optical (UK) Ltd Planoconvex Lens N-BK7 6mmdia x 8mm F.L. Uncoated LPV0806

Planoconvex lenses have one plane and one convex surface and have a positive focal length. Planoconvex lenses are typically used for focusing or collecting light in optical systems. Plano-convex lenses are normally made of a medium index crown glass such as BK7 or equivalent or BaK4 or equivalent however for lower spherical aberrations lenses high index glass is used typically SF11 or equivalent. Planoconvex lenses form a moderate quality image close to the axis but usually the chromatic aberration is serious. They are generally used as elements within a more complex lens system or optical instrument in imaging systems, lasers and detectors. Knight Optical stock planoconvex lenses are available from 2.5mm dia up to 100mm dia in a full range of focal lengths to meet most applications.
