Overview

Coatings for harsh environment

For more than a decade iXblue has developed a unique know-how in the design of optical fibers in radiative environments such as nuclear power plants, high energy physics labs, nuclear waste repository sites and even all the way into space. iXblue develops and maintains a comprehensive product line of fibers designed to fit many of such applications. Our fibers can be used for data transmission, sensing or experiment monitoring.

More fibers are available on stock and we have furthermore the ability to custom design your fiber based on your specific application. Do not hesitate to contact us with your specific technical requirements.

  • Combined effect of radiation and temperature: towards optical fibers suited to distributed sensing in extreme radiation environments

    G. Mélin, A. Barnini, A. Morana, S. Girard, P. Guitton & R. Montron

    30th Conference on Radiation and its Effects on Components and Systems (RADECS 2019) – September 2019

    Combined effect of radiation and temperature on the response of polyimide coated radiation hardened single-mode fibers is investigated in the context of distributed monitoring of large nuclear infrastructures. Radiation induced attenuation (RIA) is evaluated for doses ranging from 1 to 10 MGy(SiO2) and temperatures up to ~250 °C.
