Factory Price Custom Precision Grade Optical 1-200Mm Clear Sapphire Spherical Optical Glass Half Ball Lens X-P25B1T5501B
Half-Ball lenses are a kind of convex lenses in hemispherical shape that made of optical glass with good transparency and refractive parameters. It is usually made by cutting Ball Lenses in half. Material: BK7, sapphire, FS, Si, Ge, ZnS and so on Diameter: 0.50mm-150mm Tolerance: 0.001-0.003 Sphericity: 0.001 Surface Quality: 20-10 or better Coating: Optional People also ask: What is a half ball lens? Ball lenses are completely spherical lenses most commonly used to couple light in and out of fibers.
