Assemblies consist of opto-mechanical and electro-optical components that incorporate standard products in combination with custom configured fused silica and precision optical products. Added optical or fluid features such as micro-machined end tips, metal terminations, or precision couplings can be included. Customer requirements and/or specifications help to determine whether standard products or custom designed optical and mechanical parts are required.

Assemblies can include optical, electrical, mechanical and fluid functions in a single, unit. Combining optical fibers, mechanical holding and mounting hardware and fused silica capillaries, they may be used to transfer and/or manipulate light and/or fluids from one position to another. Most assemblies are based on specific user requirements. These can vary in complexity from a single, finished, optical fiber (with or without end-terminations) to a complex, branching assembly, combining the advantages of fused silica light guides and/or fluid guides, into an integral unit.

Optical fiber or fused silica capillaries can be clustered into bundles at one end and fanned-out into various configurations at the opposite end. Special end shapes can be micro-machined directly onto the optical fiber or capillary, saving bonding and coupling losses. Termination style and technique, jacketing, and fiber type can be specified to ensure optimum system performance.

Our extensive medical, industrial, scientific experience is a valuable resource in designing and building fiber optic assemblies for applications ranging from laser power transmission to process control instrumentation to short distance data communication. In order to do our best for you, we will need answers to as many of the following items as is possible.

Application Description
Wavelength(s) of Operation
Input Source Types (diode, laser, broadband, CW, pulsed)
Power Levels (peak, pulse, rate, repetitions, energy density)
Length, with Tolerances
Environmental, Chemical, Use Conditions
Level of Reliability
Launch Conditions (spot size, input NA)

Bio-compatibility or Sterilization Required*
Flexibility Requirements
Sketches and Concept Drawings
Configuration (straight or multi-leg)
Input/Output Functions (sensing, power delivery, diffusion, etc)
Size Constraints of Fiber, Bundle, Jacket, and Assembly

* The end manufacturer is responsible for bio-compatibility and sterilization testing and validation studies.

Bending Diameter(s) and Locations
Temperature Range (operation, storage, intermittent)
Cost Guidelines and Targets
Flammability
Test Requirements
Quantity & Delivery Requirements (prototype and production)

In response to the details of the above design parameters, our engineers will be able to take your requirements and help you generate an initial design solution. Before any design is finalized, the following items will generally have to be specified. This helps to generate performance, cost and test requirements. It will become the definitive guide when production of the assemblies begins.

Fiber or Capillary Type
Fiber Size (core, clad, buffer)
Proof Test Level
Overall Assembly Size
Termination Type (SMA, ST, shaped, other)
End Finish (polish, cleave, lens)
Achievable Tolerances

Numerical Aperture (NA) of fiber
Shaped End-tips
Insertion Loss
Fiber Anchoring (epoxy, crimp, other)
Jacket, Buffer, Strength Member Materials
Test Requirements
Bend Diameters (loss budget, short-term & long-term minimums)
