Optical Lenses, which may consist of a single or multiple elements, are used in a wide variety of applications from microscopy to laser processing. Many industries utilize Optical Lenses, including life sciences, imaging, industrial, or defense. As light passes through a lens, it is affected by 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) or Double-Concave (DCV) lens causes the light traveling through the lens to diverge. Achromatic Lenses are ideal for applications requiring color correction, while Aspheric Lenses are designed to correct spherical aberration. 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). A plano-convex lens is compose of a plane and convex surfaces, has a positive focal length. It is suitable for collecting and focusing light, and is a ideal optical element in the application of emitters, detectors, lasers, and fiber optics.

Hard coating The uncoated lenses are easily subjicted and exposed to scratches, thanks for hard coating, the lenses can effectly scratchresistance. AR coating/Hard multi coating AR coating also called hard multi coating, just means coat an anti-reflective film on the hard coating. It can perfectly reduce light reflection and glare, enhance functional and charity of your vision. 1. Are your company a manufacturer or a trade company?
