Optical Glass Lens Magnifying Lens Sphere Convex Lens Optical Lenses are optical components designed to focus or diverge light. Optical Lenses, which may consist of a single or multiple elements, are used in a wide variety of applications from microscopy to laser processing. Worldhawk can supply Plano Convex Lens, Double Convex Lens , Plano Concave Lens, Double Concave Lens, Meniscus Lens, Achromatic Lens and aspheric Lens. Optical glass lenses have a wide variety of applications. Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) lenses are ideal for transmitting the Infrared (IR) spectrum, while Fused Silica is well suited for the Ultraviolet (UV).
Plano-convex lens, aslo called positive lens, is used to converge incident light to a spot on the axis, at a certain distance behind the lens, which is knowed as focal length. It can form both real images and virtual images(for magnifier) on the two sides. The materials to make plano-convex lens can be BK7, Fused Cilica, sapphire and CaF2 etc., for different applications.This model are commonly applied in many devices including telescopes, collimators, magnifiers,optical transceivers, condensers and other optical display or imaging optical systems. AR/NIR or other coatings are available according to the applications.
