Product Description

Polarization Maintaining

Short Wavelength Fibers

Coherent’s industry leading 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 great.

Typical Applications

Laser pigtailing
