• Emission, Fluorescence and Absorption Spectroscopy

• Illumination

• Splitters – Single input to multiple outputs

• Combiners – Multiple inputs to a single output

• Mapped arrays for position sensing or generating specific output or       input distributions

• Linear arrays for spectrometer slit matching

• Precision spaced arrays for diode array coupling or optical switching


  • Flexibility and excellent throughput by using multiple fibers of the highest quality.

• Can be shape changed, meaning the cross section, or aperture, of each end may be different, e.g., spot to slit.

• Aperture shaping allows for aperture matching.

• Transmission from 180nm through 2200nm and longer.

• Standard and custom end fittings available.

• Harsh environments (high temperature, high vacuum etc.).


  Bundles and arrays are simply fiberoptic assemblies comprised of multiple fibers.

Using multiple fibers provides several important benefits:

• Apertures over 1mm in diameter are easily and cost effectively accommodated.

• The flexibility of a bundle of multiple smaller core fibers is superior to the flexibility from a single larger diameter fiber.

• Multiple fibers can be configured in virtually any cross section imaginable and the two ends may have different cross sections.

  RSOF fabricates bundles or arrays using all of the standard types of fibers. These include silica core/silica clad, silica core/plastic clad, all plastic, borosilicate glass or other more exotic constructions. These fibers exhibit NAs of 0.12 to 0.66. RSOF offers one of the widest ranges of materials possible in order to tailor products to both technical and economic requirements.

RSOF can provide standard end fittings like ferrules or OTS connectors but can also provide custom end fittings to suit your specific or OEM applications.



  Fiberoptic bundles and arrays need to be specified with regard to their aperture shapes and sizes, lengths, fiber type and end terminations, along with providing any environmental concerns.

RSOF's specifying system is an effort to accommodate the most commonly ordered bundles and arrays, but the

possible configurations that fall under this product area are limited only by the imagination and the diverse applications that require fiberoptic assemblies like these. If the desired product does not conform to the specifying system please give RSOF a call and one of our application specialists will help you.

The possible end terminations or end fittings are also unlimited. Some standard fittings are shown here but we are able to provide virtually any configuration that can be made. Please call us to discuss your needs.
