FFC Series Adjustable Fiber Collimato

Product Description

• Ø12 × 22.1 mm, non-magnetic stainless steel housing
• Adjustable-focus fiber collimator for collimating light output from fiber
• Optional broadband anti-reflection coating for visible or near-infrared
• For single-mode fiber patch cords; FC/PC and FC/APC connector options
• Simplifies fiber coupling and detection systems

Fiber collimators are pre-aligned optical devices that collimate divergent beams from fiber into parallel beams (or couple parallel beams into fiber).

Technical Notes

Rotating the external head shifts the internal aspheric lens along the optical axis to adjust the distance between the lens and fiber end face. This optimizes collimation or coupling. The knurled locking ring secures the focus position once set.

For fiber-to-fiber coupling, the FB series fiber U-stage is recommended. Compatible with POL-12 mounting holes or OAD-12 collimation holes, this collimator features an SM1 (1.035”-40) external thread for direct integration into U-stages, optical mounts, or cage systems.
