Product Description



Customed N-BK7 Optical Glass Ball for Medical Devices and Industrial Lasers


. ‌Glass Material

  • Composition‌: N-BK glass is a type of borosilicate crown glass, composed primarily of silica (SiO), boron oxide (BO), sodium oxide (NaO), potassium oxide (KO), aluminum oxide (AlO), and small amounts of other oxides for refining and stabilizing purposes.
  • Manufacturer‌: Custom-made, indicating that these glass balls can be tailored to specific dimensions, tolerances, and optical requirements.

. ‌Properties

  • Optical Properties‌: N-BK exhibits excellent optical transmittance in the visible and near-infrared spectrums, with low dispersion and a refractive index close to that of crown glass standards.
  • Physical Properties‌: High hardness and durability, resistant to thermal shock and chemical attack, making it suitable for harsh environments.
  • Dimensional Accuracy‌: Precision manufacturing ensures tight tolerances on diameter, sphericity, and surface finish.

. ‌Function

  • Optical Components‌: Used in lenses, mirrors, prisms, and other optical components for imaging, illumination, and measurement systems.
  • Calibration Standards‌: Serves as a reference for optical alignment, calibration, and testing equipment.
  • Laser Applications‌: Enhances laser beam quality and performance by minimizing dispersion and aberration.

. ‌Applications

  • Telescopes and Microscopes‌: Enhances image clarity and resolution in optical instruments.
  • Photography and Cinematography‌: Used in lenses to capture high-definition images and videos.
  • Medical Imaging‌: Contributes to the accuracy and precision of diagnostic imaging equipment.
  • Aerospace and Defense‌: Critical in guidance systems, targeting devices, and other high-precision optical instruments.
  • Industrial Lasers‌: Improves the performance and reliability of laser cutting, drilling, and welding machines.
