Optical Lenses are optical components designed to focus ordiverge light. Optical Lenses, which may consist of a single or multipleelements, are used in a wide variety of applications from microscopy to laserprocessing. Many industries utilize Optical Lenses, including life sciences,imaging, industrial, or defense. As light passes through a lens, it is affectedby the lens’ profile or substrate. A Plano-Convex (PCX) or Double-Convex (DCX)lens causes light to focus to a point, while a Plano-Concave (PCV) orDouble-Concave (DCV) lens causes the light traveling through the lens todiverge. Achromatic Lenses are ideal for applications requiring colorcorrection, while Aspheric Lenses are designed to correct spherical aberration.Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) lenses are ideal fortransmitting the Infrared (IR) spectrum, while Fused Silica is well suited forthe Ultraviolet (UV).
A lens is a transmissive optical device that affects thefocus of a light beam through refraction. A simple lens consists of a singlepiece of material, while a compound lens consists of several simple lenses(elements), usually along a common axis. Lenses are made from transparentmaterials such as glass, ground and polished to a desired shape. A lens canfocus light to form an image, unlike a prism, which refracts light withoutfocusing. Devices that similarly refract radiation other than visible light arealso called lenses, such as microwave lenses or acoustic lenses.
