Photonics - Custom Assemblies
|
|
| When your needs fall outside the box, we can help. Our custom assemblies vary from simple, like a special length or a different termination, to the highly complex, like a multi-leg assembly with bundle-to-line conversion. You control the options, and we control the quality and quick delivery! TYPES OF CUSTOMIZATION:
• Length
• Fiber type
• Termination / Connectors
• Materials for jackets, terminations, furcation blocks, and epoxy
• Configuration (branching, multiple fibers, probes, bends, feedthroughs)
• Custom laser marking of boot (part number, company name, logo) By choosing the right combination of options, you can create an assembly for harsh environments, or a probe for fluorescence. There are a lot of possibilities, so let us help you find the right mix. Options shown in plain text are considered "standard", and can be delivered quite quickly. Options shown in italics may require additional leadtime for materials or special machining at our in-house shop. Contact us at photonics@gulffiberoptics.com! |
| ASSEMBLY TYPES | | Patch Cables | -Single continuous light path
-Can be single fiber or bundle
-Bundle to line conversion options | | Bifurcated Cables | -Two continuous fiber paths with different end points
-Can be single fibers, bundles, or both
-Variable bundle ratios optional (20:80, etc.)
-Tri-furcated and higher branching optional
-Branching on both ends | | Split Cables | -Looks like a bifurcated cable, but fiber is not continuous
-Geometrical overlap of fibers at the branching point
-Poor efficiency, but can mix 2 light sources | | Reflection probes | -Can be 6 illumination around 1 read or other configuration
-Mixed fiber types optional(i.e., UV illumination, VIS read)
-Mixed fiber sizes & larger bundles optional
-Multiple branching optional | | Dip probes | -Double-pass transmission path
-Path lengths from 4mm+ | | Vacuum feedthroughs | -Threaded bolt with an O-ring optional
-KF & conflat flanges optional |
Length options:
- 40mm to 40m (including connectors, tip-to-tip)
- Plus or minus 0.1m standard tolerance unless specified
- Longer & shorter assemblies available upon request
Fiber types available:
- Borosilicate fiber - 30 or 50um diameter (0.55 or 0.62 NA)
~380-2000nm transmission range
~Ideal for bundles & low-cost applications
- Silica/silica fiber - 50, 100, 200, 400, 600, 800, 1000um core (0.22 NA)
~UV/VIS (300-1100nm)or VIS/NIR (400-2500nm) wavelengths
~polyimide buffer on 50-800um fiber
~acrylate buffer on 1000um fiber
- SMF-28 single mode fiber - telecom (NIR)
- Single mode fibers available for visible transmission ranges also
- Plastic/Polymer fiber available - large core, high NA
- Metal-coated fibers available - aluminum, gold
Termination/Connector options
- ST - keyed with alignment pins, quick release (no threads); telecom
- FC - keyed with alignment pins, but threaded; telecom
- SMA 905 - the standard for fiberoptic spectrometers
~standard or enhanced styles
~PEEK (non-conductive, for magnetic environments)
~ceramic ferrule for tighter concentricity tolerance (laser & single mode fiber applications)
~micro EDM linear array of fibers - Bare fiber end - specify length to be exposed from jacket
~cleaved or polished end
~transition to jacket can be loose, potted with epoxy, or fixed with a connector (fiber protruding) - Ferrules & probes
~1/4" & 1/8" diameter, 3" long stainless steel is standard
~custom diameters & lengths
~brass, copper, aluminum, PEEK, Delrin available (inquire about other materials)
~90 degree or other radial bend
Material options for furcation blocks, probes, and ferrules:
- Delrin - hard, machinable plastic, non-stick, black
- Teflon - softer than Delrin, higher temperature resistance, white
- PEEK - non conductive & non-corrosive - ideal for use in magnetic fields & corrosive environments
- Aluminum - lightweight, low-cost, & non-corrosive
- Stainless steel - corrosion-resistant, harder than aluminum or plastics
|
 | Jacket materials available:
- PVDF zip tube - low cost & flexible, but kinks are possible
- Silicone monocoil - crush resistant, will not kink, higher temperature
- Fully interlocked stainless steel BX - even higher temp & crush resistance; fiber protected from snapping (unlike fully expanded BX)
- Medical silicone sheath - FDA & food grade, autoclaveable if assembly is built with the proper process (please specify)
- Stay-put stainless steel interlock - fully interlocked, holds shape once bent
- PVC monocoil - crush resistant, but lower temperature range & no strength member
- Some jackets available in multiple colors - inquire for selection
| | Jacket Type | OD's Available | Inner members | Temperature Range | Bend Radius** | | PVDF zip tube | 0.149" | Strength - Kevlar
Protection - Teflon | -4F <-> 176F
(-20C <-> 80C) | 2.5" | | Silicone monocoil (silicone over stainless steel) | 0.229" | Strength - Nomar
Protection - Teflon | -60F <-> 460F
(-51C <-> 238C) | 1.5" | | Fully interlocked stainless steel BX | 0.266" | Strength - Kevlar available
Protection - Teflon | -60F <-> 536F
(-51C <-> 280C) | 2.0" | | Medical silicone | 0.200" - 0.375" | Strength - none
Protection - None | -60F <-> 536F
(-51C <-> 280C) | Depends on OD (inquire) | | Stay-put stainless steel interlock | 0.275", 0.410" | Strength - Kevlar available
Protection - Teflon | -60F <-> 536F
(-51C <-> 280C) | 3.5" | | PVC monocoil | 0.140", 0.235" | Strength - none
Protection - Teflon | -4F <-> 212F
(-20C <-> 100C) | 1.0" for 0.140" OD, 2.0" for 0.235" OD |
| ** NOTE: For best reliability, fiber should not be bent to tighter than 200x its diameter short term, or 400x its diameter long term. |
| Epoxies:
- EPO-TEK 353 ND - industry standard
- EPO-TEK CF6-2 - high temperature, often used for medical applications
- EPO-TEK OM125 - low-expansion, good for large core & plastic fibers
- Ceramic Cements - very high temperature assemblies
