■Product Overview
Bynet Square Capillary Tubes are high-precision microstructured components designed for fiber alignment, positioning, bonding, and encapsulation in advanced optical devices. Manufactured with tightly controlled dimensional tolerances, these capillaries ensure consistent fiber placement and mechanical stability during assembly processes.
The square geometry provides superior anti-rotation characteristics, stable fiber seating, and improved alignment accuracy compared with round capillaries. They are widely used in micro-optical packaging, fiber arrays, PLC splitters, micro-lenses, sensors, coupling modules, and fiber connector sub-assemblies.
Bynet leverages high-purity silica, borosilicate glass, engineered polymers, or stainless-steel materials to meet diverse optical and mechanical requirements, ensuring compatibility with high-temperature bonding processes, adhesives, laser welding, and automated assembly lines.
■Key Features
- High-precision square geometry: Enables accurate fiber placement and prevents rotational misalignment, ideal for multi-fiber alignment fixtures.
- Ultra-tight dimensional tolerances: Typical inner/outer tolerance down to ±1–2 μm, guaranteeing consistent optical coupling performance.
- Multiple material options: Available in fused silica, borosilicate glass, polymer composite, ceramic, and stainless steel depending on application needs.
- Excellent thermal stability: Suitable for high-temperature curing, epoxy bonding, laser welding, and harsh-environment operation.
- Smooth inner surface finish: Reduces fiber insertion friction and protects fiber jackets during assembly.
- Customizable geometries: Square, rectangular, segmented, coated, and multi-channel structures available on request.
- High resistance to chemicals and solvents: Compatible with all major optical adhesives and encapsulation materials.
