Request InfoPhoton Kinetics Inc.The S14 Fiber Refractive Index Profiler from Photon Kinetics is a tool for developers and manufacturers of optical fiber. The device assesses waveguide structure and determines fiber geometric properties such as core and cladding diameter, concentricity, and noncircularity. The ability to calculate both mode field diameter and effective area of fibers using the acquired refractive index profile data is included in the standard software. This new capability, combined with graphical user interfaces for both R&D and routine production measurements, is ideal for use in fiber refractive...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/28/2022Heat Cure EpoxyThe ÅngströmBond® AB9123EP heat cure from Fiber Optic Center Inc. is an epoxy with short lead times and consistent dot-sized dispensing solutions for fiber optic applications. ...Photonics.com 4/27/2023Optical Time Domain ReflectometersThe D-Series of Optical Time Domain Reflectometer (OTDR) solutions from EXFO are advanced field testing tools that deliver highly accurate measurements to characterize and validate fiber links. ...Photonics.com 5/9/2023Optical FibersThe VHS400 Verrillon® series of specialty optical fibers from AFL are designed to withstand harsh environments within the oil, gas, industrial, geothermal, and military markets.
