The high-numerical aperture and low-OH content of multimode step-index UltraSil Optical Fibers provide a wide window of operability to the end-user. Low OH concentration is especially effective for using these fibers in near-IR spectroscopy applications.
For laser delivery, the HCS® fluoroacrylate coating preserves cladding modes through bends and distributes lost power over a greater area—lowering the probability of “hot spots.”
For high-temperature performance, we recommend PYROCOAT® polyimide coating. This coating strips cladding modes for enhanced performance in sensing and spectroscopy applications.
