Optical Fiber & Probe Overview
Ocean Optics is the most versatile supplier of optical
fibers and accessories for spectroscopy in the industry.
We offer
everything from one-off patch cords and custom assemblies, to OEM builds
for all sorts of applications. Our fiber accessories, fixtures and fiber
assembly kits allow you to easily connect or manipulate fibers, and
integrate them into tricky experiment set-ups.
Optical fiber technology
has been paramount to our success and makes possible our “take the
instrument to the sample” maxim. Fiber is the nucleus of our analytical
instrumentation and accessory design philosophy. And it’s optical fiber
technology that helped us create the world’s most flexible line of sensing
instruments.
 At the fiber’s core is pure silica; it’s the diameter of
the core that you need to consider when purchasing an optical fiber
assembly. (The core diameter is often in the product’s item code. For
example, the QP600-UV-VIS has a 600 µm diameter silica core).
Surrounding
the core is a doped-fluorine silica cladding. A buffer material is then
applied. A buffer coats the core and cladding, strengthens the fiber and
reduces stray light even further. In most assemblies polyimide is used as
the buffer; other assemblies use aluminum or acrylate. Then a jacketing is
applied over the core, cladding and buffer to protect the fiber and
provide strain relief. For off-the-shelf Premium-grade “Q” Optical Fiber
Assemblies, the standard jacketing is stainless steel silicone monocoil.
For off-the-shelf the Laboratory-grade Optical Fiber Assemblies, the
standard jacketing is zip tube blue PVDF. (There are several other
jacketing options when creating a custom assembly.) Precision SMA 905
Connectors terminate the assembly and are precisely aligned to the
spectrometer’s slit to ensure concentricity of the fiber. Finally, captive
end caps protect the fiber tips against scratches and contaminants.
Our optical fiber and probe assemblies are clearly and
cleanly labeled in three ways so that you always know the following about
your assembly: its name, its core diameter and its most efficient
wavelength region.
A color band tells you the diameter fiber with which you
are working
The assembly's boot collar color lets you know the fiber
type and the most efficient wavelength range in which your fiber will
work.
