Description

2D Matrix Fiber Arrays with Microlenses: Precision Beam Shaping

High-Performance Collimated Output with Active Alignment

Our 2D Optical Fiber Collimator Arrays are engineered for high-density applications requiring superior beam control. By utilising Active Alignment technology, we pair 2D fiber arrays with high-precision Microlens Arrays (MLA) to deliver collimated output beams with industry-leading accuracy.

The compact architecture supports a high volume of beams while maintaining an angular deviation of less than 0.2°. To ensure seamless integration and durability, the entire assembly can be housed in a rugged stainless steel flange.

Why Choose Active Alignment?

Standard alignment often falls short in high-speed or high-precision environments. Our active alignment process ensures:

Minimal Tilt Errors: Precise positioning of each fiber relative to the MLA.
Customisable Optics: We select Microlens Arrays based on your specific beam diameter, fiber type, and operating wavelength.
Precision Geometry: Fully customisable 2D layouts, including bespoke spacing and pitch dimensions.

Key Advantages

Superior Accuracy: High-precision beam positioning with minimal tilt error.
Full Customisation: Tailored array dimensions, fiber spacing, and housing designs.
Versatile Connectivity: Compatible with standard interfaces including E2000, LC, SC, FC, ST, MTP/MPO, and MMC connectors.
Broad Fiber Support: Optimised for Single Mode (SM), Polarization Maintaining (PM), and Multi-Mode (MM – Step/Grin) fibers.
Robust Integration: Stainless steel flange housing for easy handling and long-term reliability.

Industry Applications

Our 2D Matrix Fiber Arrays are the backbone of advanced optical systems across several sectors:

Telecommunications & Data Canters: Powering MEMS switches for high-speed, reliable optical routing.
Automotive & LiDAR: Essential for precision beam shaping in 3D mapping and autonomous vehicle sensing.
Aerospace & Robotics: Integrated into multi-channel rotary joints for signal transmission in radar systems and wind turbines.
