18 Years Factory Supplier Achromatic Lens - 10W-100W Glass LED lens 80MM Focusing optical glass lens, high power LED convex lens – DG
Optical Windows An achromatic lens or achromat is a lens that is designed to limit the effects of chromatic and spherical aberration. Achromatic lenses are corrected to bring two wavelengths (typically red and blue) into focus on the same plane. The most common type of achromat is the achromatic doublet, which is composed of two individual lenses made from glasses with different amounts of dispersion. Typically, one element is a negative (concave) element made out of flint glass such as... -

China New Product Optical Glass Lens - double convex lens – DG
Bi-Convex Lenses are the best choice where the object and image are at equal or near equal distance from the lens. When the object and image distance are equal (1:1 magnification), not only is spherical aberration minimized, but also coma, distortion, and chromatic aberration are identically canceled due to the symmetry. Bi-convex lenses function similarly to plano-convex lenses in that they have a positive focal length, and focus parallel rays of light to a point. Both surfaces are spherica... -

Lowest Price for Aspheric Lens - Precision Polished Aspheric Lenses – DG
Small aspheric glass lenses can be made by molding, which allows cheap mass production. Due to their low cost and good performance, molded aspheres are commonly used in inexpensive consumer cameras, camera phones, and CD players.They are also commonly used for laser diode collimation, and for coupling light into and out of optical fibers. Larger aspheres are made by grinding and polishing. Lenses produced by these techniques are used in telescopes, projection TVs, missile guidance systems, an... -

Factory Cheap Acrylic Fresnel Lens - Glass Fresnel Lens Dia 150 Borosilicate Glass Optical Collimator Lens for Projector – DG
Product Description Fresnel lens, succession of concentric rings, each consisting of an element of a simple lens, assembled in proper relationship on a flat surface to provide a short focal length. The Fresnel lens is used particularly in lighthouses and searchlights to concentrate the light into a relatively narrow beam. Fresnel lenses are a special kind of optical lenses, where the surface profile contains annular steps such that a given focal length can be achieved with a substantiall... -
