Aspherical Molded Glass Lenses with Metal Holder (Coupling Type)


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.
  • Highly reliable anti-reflection coating resolves problem of degradation in high-temperature or high-humidity environments.
  • FLAH Series 1:1 low-coupling lens such as for waveguide coupling.
  • Varieties with anti-reflection coatings for light in the visible spectrum also available.
