Product Name: Optical Sapphire Glass Half Ball Lens for Laser Fiber From China Model NO.: VY003 Coating: Per Your Request Customized: Customized Certification: RoHS, ISO9001 Lenses Color: Clear Material: Optical Glass Shape: Ball, Hemisphere Transmittance: >95% Type: Ball Usage: Optical Dia. 25.4mm: 1 Inch Surface Quality: 20/10 Dimension Tolerance: +/-0.1mm Surface Accuracy: Lambda Trademark: VY or OEM Transport Package: as Requested Specification: RoHS Origin: Cn HS Code: 9001909090 Product Description >> Product Description Spherical Ball Lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres has the benefit of fitting into smaller packages.Ball lenses are highly polished spheres made of optically transparent homogeneous materials. Carefully controlled manufacturing process produces spheres with precise diameters and unsurpassed surface quality.We supply optical spherical ball lens,Half-ball (hemispherical) lenses are ideal for applications such as fiber communication, endoscopy, microscopy, optical pick-up devices, and laser measurement systems.>> SpecificationSpecification of optical1.8mm ball lens we manufactured:Material: BK7, LaSFN9 glass,Ohara S-LAH71 glass or other optical glassSphericity: 0.001mmSurface Quality: 20-10Diameter: 1.8mm+/-0.005Range of diameterDia.0.7mm-Dia.400mmRange of curve radiusR1.5-R∞ etc.Tolerance of diameter+/-0.1, +/-0.01, +/-0.005 etc.Surface accuracyλ , 1/2λ , 1/4λ , 1/10λ etc.Tolerance of Thickness+/-0.1, +/-0.05, +/-0.01 etc. Centration+/-2′,+/-1′ etc.Aperture N5, 1 etc.Irregularity ΔN2, 1, 0.5, 0.2 etc.Surface quality60/40, 40/20, 20/10, 10/5 etc.>> Company Introduction>>Related Products VY Optics could also manufacture and design other optical elements, includingachromatic lens,dome lens,filter,prism,ball lens,cylindrical lens,optical mirrors,spherical lensandrod lens, we can fabricatehigh-precision lensas per your requested.>>FAQQ:Do you provide samples?
