Product Description Product DescriptionOptical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. A Plano-Convex or Double-Convex lens causes light to focus to a point, while a Plano-Concave or Double-Concave lens diverges the light which traveling through the lens. Achromatic Lenses are ideal for correcting color, aspheric lenses are designed to correct spherical aberration.Ge, Si, or ZnSe lenses are suited for transmitting the Infrared (IR) spectrum, fused silica is well suited for the Ultraviolet (UV). Double Concave Cylindrical LensCylindrical Lenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylindrical Lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.Diameter Tolerance+0.0/-0.1mmCenter Thickness Tolerance±0.1 mm..Focal Length Tolerance±1%..Surface Quality60/40, 40/20 or better..MaterialBK7, UVFused silica, Ge,CaF2, ZnSeClear Aperture>90%Centering<3 arc minCoatingCustomBevelProtective bevel as neededShenyang Ebetter Optics Co., Ltd. has been engaged in more than 20 years.
