For applications requiring multi fiber transmission of higher laser power, SQS provides dedicated laser beam delivery cables with thermally fused bundle ends. These assemblies are engineered separately from standard fiber bundles because laser power handling, optical efficiency and thermal behaviour require application specific design.
Linear fiber optic bundles arrange the fibers in one or more rows at the optical interface. They are suitable for applications where the receiving or emitting optical system uses a linear geometry, including spectrometer entrance slits and line illumination. SQS linear bundles can be manufactured with customer specified fiber mapping, fiber dimensions, connector interfaces and ferrules.
Round fiber optic bundles combine multiple fibers into a circular optical interface for efficient collection or delivery of light. Fiber count, core dimensions, overall bundle diameter, connector interface and mechanical protection can be adapted to the application.
Round to linear fiber bundles convert a circular fiber arrangement at one end into a linear arrangement at the other. This geometry is particularly useful when light collected from a circular source area needs to be coupled into an optical device with a narrow entrance slit, such as a spectrometer. Defined fiber mapping can maintain the required relationship between individual fiber positions at both interfaces.
Linear fan out assemblies distribute individual fibers from a common linear interface into separate fiber legs. Individual outputs can be identified according to their position in the linear input arrangement, enabling controlled routing and defined fiber mapping.
Round fan out bundles split fibers from a common circular interface into individually terminated outputs. The configuration can be adapted according to fiber count, connector interface, mechanical protection and mapping requirements.
Fiber optic reflection probes combine optical paths for illumination and signal collection within one fiber assembly. SQS reflection probe configurations can connect a light source, measurement area and spectrometer while allowing the fiber arrangement at the spectrometer interface to be adapted to the optical instrument.
SQS designs and manufactures custom fiber optic bundles for controlled light collection, transmission, distribution, and beam reshaping. Fiber type, count, geometry, mapping, connector interface, ferrule design, mechanical protection, and bundle length can be configured to match the optical and mechanical requirements of the application. Available configurations include round and linear bundles, round-to-linear converters, fan-out assemblies, reflection probes, and specialized multi-fiber cables for laser beam delivery.
Fiber bundles are available in round, linear, square, hexagonal, cross, and custom geometries. For non-round geometries, fibers are bonded into a fused silica cylinder with a customer-defined aperture fabricated by SQS SLE technology, such as slits, squares, crosses, fiber groups, or other custom patterns. The cylinder is then integrated into the connector or probe.
For precise linear fiber positioning, we offer custom V-groove fiber arrays for 125 µm cladding fibers, with a minimum 127 µm center-to-center pitch and typical positioning accuracy of ± 0.5 µm.
Linear structures can also be realized using standard MT ferrules with a 250 µm fiber pitch and typical positioning accuracy of ±0.5 µm. MT ferrules support up to 16 fibers in a single row, with multi-row configurations available for higher fiber counts.
For precise 2D positioning, Matrix fiber arrays are available with typical accuracy of ± 1 µm and a minimum pitch of 350 µm in X and Y axis.
Fiber mapping defines the position and sequence of individual fibers at the bundle input and output, enabling controlled fiber-to-fiber correspondence.
Fiber selection depends on wavelength, optical power, numerical aperture, environmental conditions, and transmission requirements.
SQS fiber bundles can use:
Multimode fibers are available with core diameters ranging from 50 to 1500 µm and with circular, square, or octagonal core geometries. The fibers are typically bonded directly into the connector, ferrule, or probe without the primary coating. For polyimide-coated fibers, the primary coating may either be retained or stripped at the connector, depending on the specific application.
Bundles can be terminated with SMA905, FC, ST, MT, V-groove fiber arrays, 2D fiber matrix, collimators or custom interfaces (connectors, probes). Custom ferrules can be designed to meet specific requirements for optical aperture, dimensions, and fiber arrangement. Available materials include stainless steel, invar, kovar, fused silica, and other application-specific materials.
For ultra-high vacuum (UHV) applications, we offer UHV-compatible SQS connector interfaces, including FC/PC, FC/APC, SMA905, and custom interfaces made from 304L/316L stainless steel. These assemblies are manufactured using UHV-compliant processes and low-outgassing adhesives to ensure reliable performance in demanding vacuum environments.
Protective solutions include stainless steel (304L/316L), PVC, PTFE, PVDF, and PEEK. Vacuum-compatible and UHV configurations are available according to the application and material requirements.
For vacuum applications, fiber bundles can be equipped with fiber-optic vacuum feedthroughs for reliable fiber sealing and optical transmission through vacuum chambers, including custom flange configurations.
