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
• Spectroscopy
• Sensors
• Bio-medical
• Metrology
Features & Benefits
• Panda-style configuration — Superior performance, intrinsically good radiation performance
• Tight specifications — Highly deterministic results, highest product yield
• High Proof Test — Low risk of mechanical handling failure
• High fatigue failure resistance — Longest service life
