Description:
ASML Navaigation's 850 nm PANDA-style PM Gyroscope fibers have extremely high birefringence and exceptionally tight dimensional specifications, critical for manufacturing high precision, high-performance gyro-coils. High consistency and extreme end-to end control of optical properties provide particular advantage in this application by reducing fiber generated signal artifacts.
The intrinsically high level of radiation resistance allows operation for extended periods of time on low earth orbits, near and deep space, and applications where exposure to man-made radiation is expected. The Panda-style configuration is preferred over bow-tie or elliptical clad designs because of its advantages in process scalability and product uniformity. These fibers are offered in industry standard specifications and ASML’S high performance (HP) versions optimized for exceptional splicability and offering the tightest tolerance specifications available.
Features:
PANDA-style PM — Superior performance, intrinsically good radiation performance
Extremely high birefringence — Less gyroscope drift
Bend insensitive — Smaller diameter coils possible
Excellent crosstalk stability over temperature range — Minimize Shupe (insensitive to temperature drift) effects
HP version with best specifications available — Improved repeatability, coil winding accuracy and splicability Optional wavelength:850/1310/1550nm
Applications:
Interferometric sensors
Diode pigtails
Coherent beam delivery
Modulators
Delay lines
Spectroscopy
Biomedical sensors
Optical Coherence Tomography (OCT)
