CNI's industry visible and short wavelength Polarization
Maintaining fibers have superior waveguide, radiation, and
mechanical properties enabling a large variety of new critical
applications in diverse markets. High consistency and extreme
end-to-end control of optical properties provide particular
advantage in spectrographic and frequency sensitive applications.
The intrinsically high level of radiation resistance allows this
family to operate for extended periods of time on low earth orbits,
near and deep space, and in applications where risk of exposure to
man-made radiation is good.
