What are the applications of half ball lenses?
Fiber optic communication: for fiber coupling to improve the efficiency of optical signal transmission.
Laser systems: for focusing and collimating laser beams.
Imaging systems: for microscopes and cameras to improve imaging quality.
Lighting systems: for LED lighting and projection systems to improve lighting uniformity and efficiency.

How to choose between half ball and ball lenses?
Half ball lenses: suitable for applications requiring unilateral focusing, high image quality, easy installation and fixation, and low cost.
Ball lenses: suitable for applications requiring omnidirectional focusing, optical experiments and laser processing, with complicated installation and fixation, and higher cost.
The choice should be weighed according to the specific application needs and optical performance requirements.
