Product Description
Product Introduction
Elliptical core polarization maintaining fibers have excellent stability and birefringence properties, and can be widely used in fiber optic gyroscopes, current transformers, and other polarization related devices. Shanghai RAYTEK elliptical core fiber improves the uniformity and birefringence performance of the fiber through optimized core and cladding structure. Elliptical core polarization maintaining fiber belongs to geometric birefringence type polarization maintaining fiber, which is less affected by environmental temperature and has better temperature stability.
