As Sapphire was Lab-Created in 1916, Sapphire and sapphire tooling method became widely used and more cheaper than the time it’s born. From the Ingot to Rods there are several steps:

Crystal Growingà OrienteeringàDrillingàCuttingàRoundingàGrindingàPolishing.

Sapphire Rods are likely to use as wear resistant accessories more widely, but as human technology expanding, sapphire rod lens will take more place in the future. Rod lens is polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a line. The addition of this product line is part of a continued effort to support current trends toward miniaturization.
