Warranty: 3 months Customized support: OEM Place of Origin: Jilin, China Brand Name: YT Model Number: YT-278 Use: Optical Structure: Other Shape: BALL Substrate: Optical glass Diameter: 0.3-250mm Diameter Tolerance (μm): ±2.5 Index of Refraction nd: 1.589 Porosity (%): 0 Sphericity (μm): 0.64 Wavelength Range (nm): Custom Surface quality: 60/40 Focal length: Custom Request Coating: Uncoated Ball Lens Ball Lenses provide for a shorter back focal length, simplifying fiber coupling, due to the high index of refraction. Ball lenses are manufactured from a single glass substrate and can either focus or collimate light. Ball Lenses are ideal for endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications.
