Now available from Ocean Optics are XSR Xtreme Solarization-resistant Optical Fiber Assemblies for spectroscopy, which are manufactured using a proprietary process that provides enhanced UV transmission -- signal will transmit to 180 nm -- and remarkable resistance to UV degradation, making them ideal for deep-UV (<300 nm) applications. XSR Fiber comes in several core diameter sizes and lengths, and couples to Ocean Optics spectrometers and accessories via SMA 905 Connectors. Ocean Optics is the only spectroscopy manufacturer to offer XSR Fiber.

XSR Optical Fiber Assemblies are available in core diameters of 235 microns and 455 microns, in standard lengths of 25 centimeters, 1 meter and 2 meters (custom lengths also can be ordered). A 6-around-1 reflection probe version is also available. Shorter-length assemblies are recommended for applications requiring maximum UV throughput.

UV radiation below 300 nm degrades transmission in standard silica fibers, resulting in solarization (increased light absorption in the UV fiber that blocks transmission and can invalidate data). For such applications, Premium-grade XSR Xtreme Optical Fiber Assemblies are a viable alternative to less effective solarization-resistant fibers.

XSR assemblies are robust and durable; each assembly has aluminum coating, stainless-steel BX jacketing, and high-quality SMA 905 Connectors.
