PCX lenses are optical component with positive focal length. You can choose focal length/radius of curvature, material and other characteristics to build your lenses using Alien Photonics form. What is Spherical Plano Convex (PCX) Lens? Plano-Convex (PCX) lenses are very often used type of lenses. One face is polished and flat (plano, plane). The second face is curved outwards in sphere shape. This shape results in positive focal length. While plano-concave (PCV) spherical lenses are curved inwards, with negative focal length. Lenses with both surfaces curved outwards are called double-convex (bi-convex) lenses, which can bend light more significantly (shorter focal length). What is the purpose and main function of Spherical Plano-Convex (PCX) Lenses? A spherical plano-convex (PCX) lens focuses parallel light rays (e.g. laser), to a single point, enabling precise control over the beam's direction and focus. In laser-based instrumentation, these lenses help to achieve a smaller, more intense laser spot. While in various imaging devices, Alien Photonics PCX lenses enhance image clarity and detail by accurately focusing light from the subject onto the imaging sensor or eyepiece 532 nm plano-convex spherical lenses for laser scanning systems Alien Photonics spherical PCX lens made of UVFS is used to focus a 532 nm Nd:YAG laser beam in a laser scanning system, allowing for precise targeting and high-resolution imaging. The material's high transmittance at this wavelength ensures efficient light passage and minimal loss.
