Ball Lenses – Ultra-Compact Fiber Optic & Laser Collimation
Detailed Description:
Ball Lenses are spherical optical elements that offer ultra-compact collimation and focusing for fiber optic systems and laser diodes. Their symmetric spherical shape eliminates alignment sensitivity, making them ideal for high-density optical assemblies and miniaturized devices.
Key Specifications:
- Materials: BK7, Fused Silica, Sapphire, Borosilicate Glass
- Diameter: 0.3mm – 20mm (micro-ball options available)
- Focal Length: Directly proportional to diameter (n·D/2)
- Surface Quality: 60/40, 40/20
- Sphericity: High sphericity for minimal aberration
- Coating: AR coating (1310nm/1550nm for telecom, VIS for sensing)
- Tolerance: Diameter tolerance ±0.01mm (precision grade)
Applications:
Fiber optic collimation, laser diode coupling, optical sensors, medical imaging, miniaturized optical systems.
