1310 nm FC/APC Aspheric Fiber Collimator
The AFC-FC-APC-1310 delivers diffraction-limited collimation for single-mode fiber systems operating in the 1260–1360 nm O-band. Pre-aligned at the factory to sub-0.5° beam pointing stability, it provides high transmission and superior wavefront flatness for fiber-to-chip coupling and free-space optical routing.
Every Zolix collimator undergoes interferometric wavefront qualification and precision angular alignment before delivery.
