Planoconvex Lenses

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.

Apart from our stock planoconvex lenses which are available from 2.5mm dia up to 100mm dia in a full range of focal lengths with a range of AR coated wavelength options, we are able to supply custom planoconvex lenses to meet your specific requirements.

Knight Optical offer custom planoconvex lenses either uncoated or AR coated for UV, Visible and NIR telecoms wavelengths alternatively a range of Infrared materials are available from calcium flouride to germanium to meet your custom wavelength requirements. Alternatively stock lenses can be edged to smaller diameters for a quick turnaround. Custom quality grade planoconvex lenses are supplied to meet your specific design working with all standard glass types from ohara or equivalent , schott or equivalent and corning etc. either uncoated or antireflective coating centred at required wavelength or with multilayer broad band coatings. For a wide-ranging requirement, we can create bespoke planoconvex lens sets, which are ideal for research and development usage.

We are able to provide custom planoconvex lenses for general and precision applications with performance to suit your needs and budget; these are available in a range of sizes and substrates and with coating which befits your requirements.
