F1220 Series Ø12 mm Fiber Collimators

Product Description

• Ø12×20 mm, non-magnetic stainless steel housing
• Pre-aligned fiber collimators for collimating light emitted from optical fibers
• Alignment wavelength selectable from 405 nm to 850 nm
• Designed for single-mode fiber patch cords; available with FC/PC, FC/APC, and SMA905 connectors
• Simplifies fiber coupling and detection systems

Fiber collimators are pre-aligned optical components used to collimate divergent beams transmitted through fibers into parallel beams (or couple parallel beams into fibers).

Technical Notes

(1) Pre-aligned fiber collimators convert divergent fiber beams into parallel beams (or couple parallel beams into fibers). Compact Ø12 mm form factor enables easy integration into existing setups. Corrects beam divergence, minimizes optical power loss in fiber connections or beam handling, and improves system optical performance.

(2) For mounting, a collimator adapter is recommended: internal thread M11×0.5 mm compatible with this series, and SM1 (1.035”-40) external thread for direct integration into 30 mm cage systems.

(3) Can also be mounted to optical mounts using POL series fixed mounting holes or OAD series collimation mounting holes.
