Plano-Concave Lenses are used to diverge (expand) a laser beam. Choose or request material, size, focal length or ROC. Optional AR coating available. PCV lenses for laser beam expansion Plano-concave lenses are used to diverge or expand a laser beam, which is essential when a wider beam profile is required for applications like laser engraving, cutting. This is alco crucial in setups where beam conditioning is necessary before the laser interacts with the target. Alien Photonics PCV spherical lenses allow to adjust laser beam over larger area, reducing the power density and enabling a wide range of processing techniques. Focal length modification using PCV spherical lenses PCV lenses can also be used to modify the focal length of an optical system. By introducing a PCV lens into a lens assembly, the overall focal length can be increased, which is useful in applications requiring a longer working distance without changing the other lenses in the system. Plano-Concave Spherical Lenses for laser beam expansion Alien Photonics spherical PCV lens made of ZnSe is used to expand the beam of a 10.6 µm CO₂ laser in material processing applications. The ZnSe material is chosen for its low absorption at this infrared wavelength, ensuring minimal loss during beam manipulation. Telescope Plano-Concave Spherical Lenses In telescope systems requiring the correction of field curvature, Alien Photonics spherical PCV lens from N-BK7 material can be used. These lenses help to flatten the field, improving the quality of the image across the visual spectrum (400-700 nm). AR coated N-BK7 lens result in reliable optical performance and durability in changing environmental conditions.
