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.
