Micro Aspherical Glass Lens (for V-GROOVE)


Aspherical Glass Lens

Covers needs for high density in V-GROOVE market with its small, space-saving, 1mm diameter.

Applications
Min-DIL types with a silicon V-GROOVE structure, etc.
Min-DIL types with a silicon V-GROOVE structure, etc.
Features
  • Free from the wave aberration in spherical lenses. High coupling efficiency and high reliability makes this lens ideal for optical communication.
  • Mountable to small packages for high-speed laser modules.
  • Standard and custom design (different wavelength, optical characteristic and shape of lens), to suit your systems.
Applications
  • Min-DIL types with a silicon V-GROOVE structure, etc.
