High power fiber end cap

The common damage point in high-power lasers is the fiber end at the interface between silicon dioxide and air. Fiber optic end caps can solve this problem by reducing power density. In addition, our end caps are coated with AR coating at the target wavelength to reduce back reflection, which is approximately 4% for uncoated silica surfaces. It comes in two sizes: small size (Type A) and large size (Type B).
