Aspherical Glass Lenses for Visible Light


Aspherical Glass Lens

High coupling efficiency and high reliability achieved by a stainless holder integrated lens.

Applications
Features
  • Lens integrated holder enables resistance and laser welding to tightly secure the lens.
  • Free from the aberration in spherical lenses with less dispersion.
  • A variety of lenses available for different uses, including high NA lenses for high coupling efficiency and lenses integrated with peripheral parts.
  • Aspherical surface designed for light in the visible spectrum.
  • Supports anti-reflection coatings for visible light wavelengths other than the wavelength for which the lens was designed.
