Product Name: Optical Quartz Bionvex Lens Dia 25.4mm Double Convex Lenses Model NO.: OL Customized: Customized Certification: RoHS, ISO9001, CE Lenses Color: Clear Material: Optical Glass Shape: Double Convex Transmittance: >95% Type: Convex Lens Usage: Optical Transport Package: Foam Carton Inner, Then Cartons to Pack Them Specification: customized Origin: Shen Yang Product Description Product DescriptionOptical Lenses are optical components designed to focus or diverge light, widely applicated from microscopy to laser processing. APlano-Convex or Double-Convex lens causes light to focus to apoint, while aPlano-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-Convex LensesDouble-Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double-Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCX Lenses are used in arange of industries or applications.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. offers awide range of Optical lenses:Plano-convex lenses, Bi-convex lenses,Plano-concavelenses, Bi-concave lenses, Meniscus lenses, Ball lenses and Aspherical lenses.Contact Information: Person:Mager Ma Tel:+86 15702486562
