Plano-Convex Lens
ATOPTIK can process ultra-high precision optical plano-convex lenses with ultimate surface accuracy up to λ/20 and a maximum diameter of Ø150mm. A plano-convex lens consists of one flat surface and one convex surface, with a positive focal length. It can focus parallel light rays into a point or transform a point light source into a collimated beam. When in use, it is generally recommended to orient the convex surface toward the incident light to minimize spherical aberration. Applications of Plano Convex Lens 1. Optical Focusing and Collimation Plano-convex lenses are widely used in laser systems for focusing high-energy beams, such as in laser cutting and welding, or for collimating divergent light sources. Their positive focal length and ability to reduce spherical aberration make them ideal for applications where precise beam shaping and minimal distortion are essential. 2. Industrial and Scientific Instruments Plano-convex lenses are key components in various industrial and research instruments. They are commonly used in optical assemblies for projectors and periscopes, where they help direct and control light paths to improve image projection. Additionally, they play a critical role in optical calibration tasks, such as assessing and enhancing the precision of detection and measurement systems. FAQs of Plano Convex Lens Q What materials can be processed? A ATOptik can process UV-visible-infrared full band substrates, common optical materials BK7, Fused silica, Sapphire, Silicate and so on. Q What is the limited of surface accurcay? A The highest surface type can reach PV=λ/20 Q What processing methods are used? A High-speed polishing and classic polishing heads can be met, depending on the size of the lens, material, surface accuracy, and so on.
