Glass ball lenses are widely used for coupling fiber and semiconductor lasers, or photodetectors. It’s much smaller than a normal lens, and it’s completely polished, so be careful when using it. But it can reduce the size and weight of the device. With a positive focal length, used at the unit conjugate point, can eliminate all kinds of aberration.
Applications:
- Fiber optic connector
- Ball check valve
- LED encapsulating
- Bar code scanner
- Parallel photogeneration
