Half-Ball Lenses – Compact Collimation & Focusing for Fiber Optics

Detailed Description:

Half-Ball Lenses (hemispherical lenses) are ideal for collimating light from fiber optic sources or focusing light into optical fibers. Their hemispherical shape minimizes spherical aberration and provides a compact optical path, making them essential for fiber coupling and laser diode collimation.

Key Specifications:
  • Materials: BK7, Fused Silica, Sapphire
  • Diameter: 1mm – 20mm
  • Focal Length: Short focal length for compact systems
  • Surface Quality: 40/20, 20/10
  • Surface Accuracy: λ/4 @ 633nm
  • Coating: AR coating (VIS/NIR) for fiber optic wavelengths
  • Centering: Precision centering for optimal fiber coupling
Applications:

Fiber optic coupling, laser diode collimation, optical sensors, medical devices, telecom components.
