Fiber Bundles

Fiber Optic Bundles: Multiplexed Light Delivery and Collection for Advanced Optical Systems

Fiber optic bundles, also known as fiber bundles or fiber optic arrays, are essential components in systems that require simultaneous transmission of light through multiple optical paths. Used extensively in medical devices, spectroscopy, imaging systems, and industrial sensing, fiber bundles offer unmatched flexibility and performance for complex optical setups. At FindLight, we feature a broad range of fiber bundles from leading manufacturers worldwide, ready to meet your project’s optical demands.

What Are Fiber Optic Bundles?

A fiber optic bundle consists of multiple optical fibers grouped together within a common sheath or housing. These fibers may be arranged in linear, circular, square, or custom geometries depending on the application. Bundles can be made with single-mode, multi-mode, or a mix of fibers, and can also incorporate specialty fibers like polarization-maintaining or photonic crystal fibers.

Fiber bundles enable light to be collected from or delivered to multiple points simultaneously, allowing for efficient signal routing, spatial sampling, or illumination across various zones.

Key Features and Benefits

1. Multi-Point Illumination and Collection: Fiber bundles are ideal for applications requiring light collection from or delivery to multiple points, such as endoscopy or distributed sensing.

2. Customizable Geometries: Bundles can be configured in custom shapes (e.g., round-to-line, fan-out, hexagonal) to match specific imaging or sampling requirements.

3. Improved Signal Throughput: By combining the outputs of multiple fibers, bundles increase the total optical throughput, improving signal quality in low-light environments.

4. Broad Wavelength Compatibility: Fiber bundles can be constructed using materials optimized for UV, visible, NIR, or IR ranges to suit your spectral application.

5. Ruggedized Options: Many fiber bundles are available with armored jackets or heat-resistant sheathing for use in harsh or high-temperature environments.

Common Applications

Fiber bundles are widely used in:

• Medical imaging and endoscopy

• Flame and plasma spectroscopy

• Multichannel fluorescence detection

• Industrial and process monitoring

• Remote sensing and fiber-delivered illumination

• Laser beam delivery and splitting

Whether you need to sample light from several points simultaneously or deliver uniform illumination across a surface, fiber bundles provide the required scalability and precision.

Selecting the Right Fiber Bundle

When choosing a fiber optic bundle, consider the following parameters:

• Fiber Type: Multi-mode for high light throughput or single-mode for precise signal transmission.

• Bundle Geometry: Choose round-to-round, line-to-round, fan-out, or custom shapes based on your optical configuration.

• Core Size and NA: Match the fiber’s numerical aperture (NA) and core size to your source and detector.

• Connector Type: Available with standard FC, SMA, ST, or custom ferrule connectors.

• Jacket Type: PVC, metal armored, or high-temperature sheathing depending on your application environment.
