BK7/K9 Optical Glass & Sapphire Quartz Ball Lenses
Precision ball lenses available in diameters from 1mm to 10mm, manufactured from BK7/K9 optical glass, sapphire, and fused silica materials. These highly polished spheres deliver exceptional optical performance for demanding applications.
Product Overview
Ball lenses are highly polished spheres made of optically transparent homogeneous materials. Our carefully controlled manufacturing process produces spheres with precise diameters and unsurpassed surface quality. These components are essential for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling applications.
Applications
- Laser collimating and focusing systems
- Laser-to-fiber coupling
- Fiber-to-fiber coupling
- Fiber-to-detector coupling
- Fiber communication systems
- Endoscopy and microscopy
- Optical pick-up devices
- Laser measurement systems
