Name: Sapphire Light Guides
Brand: CSOC

Description

Sapphire light guides are solid optical components fabricated from high-purity single-crystal sapphire (Al₂O₃), engineered to transmit light—particularly high-power laser energy—from source to delivery point with minimal loss and exceptional durability. Unlike conventional silica fibers, sapphire light guides withstand extreme temperatures, intense optical loads, and corrosive environments, making them the preferred choice for applications where standard optical fibers cannot survive.
