The position of focus point of the glass beads is relied on its reflective Index. 

 

Shaped like perfect spheres with a smooth and shinning surface.
Remarkable strength, hardness and chemical stability. Reflective index to control it’s focus point. Uniform particle distribution. Made of Tio2, BaO glass, and their refractive index is approximately1.93 No lead, No harmful to human.
