Bare Fiber Polishing System 2023


Bare Fiber Polishing Machine

 Polish bare fiber ends into various lens shapes: large cone, small cone, wedge (screwdriver tip), angled, flat, etc. The improved fiber clamp design and various process features achieve concentricity accuracy on the micron scale
This means splitting the core (9µm) of single-mode fiber is possible.
Angle resolution: 0.10°
Angle range: 0 ~ 80°
Standard 125µM fiber spindle assembly; optional 140µM, 400µM, 600µM
We also provide contract polishing services for bare fiber.
