Why Use Aspheric Lenses?

and how to choose the right lens for diode collimation and fibre coupling Traditional spherical lenses suffer in performance due to spherical aberration. A spherical shape, though easy to manufacture, is not the ideal shape for a focusing or collimating lens. A more complex shape gives a much better result better quality collimated beams for collimating applications, a smaller spot size for focusing applications, and better image quality for imaging applications. Aspheres collimate or focus light as a single element. A single aspheric lens can often take the place of several conventional spherical lenses, resulting in a smaller, lighter, improved performance design at lower cost. The LightPath Technologies range of molded high precision glass aspheric lenses is available from Pacer. LightPath has over 10 years of experience manufacturing these small and lightweight lenses for a wide range of applications. Molded lenses have excellent piece-to-piece uniformity, and glass is the most dur
