F1115 Series Ø11 mm Fiber Collimator

Product Description

• Ø11 × 15 mm, non-magnetic stainless steel housing
• Pre-aligned fiber collimator for collimating light output from fiber
• Alignment wavelength selectable from 405–850 nm
• For single-mode fiber patch cords; FC/PC, FC/APC, SMA905 connector options
• Simplifies fiber coupling and detection systems

A fiber collimator is a pre-aligned optical device that collimates divergent beams from a fiber into parallel beams, or couples parallel beams into a fiber.

Dimensions	Ø11 × 15 mm (excluding connector)
Mount Thread	M11 × 0.5
Beam Diameter	5 mm (3 mm for 785, 830, 850 nm)
Divergence Angle	0.01°
Focal Length	15 mm
Numerical Aperture (NA)	0.17
Effective Collimation Distance	2 m

Notes:

1. Collimation is optimized for single-mode patch cords; performance degrades with multi-mode fiber. Use the specified wavelength and corresponding patch cord for best results.
2. Multi-mode or large-core fiber cannot be perfectly collimated.

Technical Notes

 

This pre-aligned collimator converts divergent fiber light to parallel beams (or vice versa). Its compact Ø11 mm size enables easy integration, corrects beam divergence, reduces optical power loss, and improves system performance.

For installation, a collimator adapter with internal M11 × 0.5 thread and external SM1 (1.035”-40) thread is recommended, allowing direct integration into 30 mm cage systems.

 

It can also be mounted on optical adjustment mounts using POL-series or OAD-series mounting holes.
