Aspherical Molded Glass Lenses with Metal Holder (Collimator 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 wide variety of lenses available to meet customer needs-high NA products for high coupling efficiency, compound products, convex holder lens.
  • Antireflection coating practically eliminates deterioration under high temperatures and humidity.
  • Custom design of visual ray wavelength, for laser projector, etc.
  • Pb-free glass type equivalent to the conventional shape and specifications are also available in all models.
