Product Family Description

  • Can be Used as Fiber Coupling Spheres or Collimating Lenses
  • Ideal Pre-Forms for Aspheric Lenses
  • Available in a Variety of Sizes
  • TECHSPEC® N-BK7 Half-Ball Lenses Also Available

TECHSPEC® N-BK7 Ball Lenses are glass spheres commonly used in fiber optic applications. Ball lenses are excellent optical components for improving signal coupling between fibers, emitters, and detectors. They are also used in endoscopy, bar code scanning, ball pre-forms for aspheric lenses, and sensor applications. TECHSPEC® N-BK7 Ball Lenses are uncoated and are optimal for wavelengths 350-2200nm. If applications require a more compact design, TECHSPEC® N-BK7 Half-Ball Lenses are also available.
