Optical Fiber & Probe OverviewThe Most Flexible Line in the IndustryOcean 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. Anatomy of an AssemblyAt 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 P600-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. Assembly IdentifiersOur 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.
Band ColorsA color band tells you the diameter fiber with which you are working
Boot CollarsThe assembly's boot collar color lets you know the fiber type and the most efficient wavelength range in which your fiber will work.
