FOG-3X50B Low precious 3 axes Closed-loop FOG

FOG-3X50B is an outstanding performance 3axes closed loop fiber optic gyroscope series developed by FOGPhotonics,inc.We use 3 pieces F600M fiber optic gyro integrated in one unit. We make full use of our developed technology of Our ASE light source. 3 Fiber optic gyros share one high powe SLD light source.Which also has the best wavelength stability.The FOG-3X50B series delivers superior precision and reliable performance at affordable cost and smaller size than other comparable gyros in general, and FOG in particular.The performance of gyros and systems can be optimized for specific requirements and applications on an individual basis. FOGs can be supplied as a stand alone single axis, or as a dual/ triad with common electronics. All FOGs are available with a flexible interface configuration.
