Low Bias Stability Fiber Optic Gyro Single Axis Open Loop Fiber Optic Gyro Sensor
Built for rugged industrial and field applications, the MFOG-091A combines precision optical technology with robust mechanical design. It maintains accurate performance under vibration (20g, 20-2000Hz) and extreme temperatures. With fast startup, simple structure, and long service life, it is the ideal alternative to Fizoptika VG091 for marine, mining, and vehicle stabilization systems.
- Optical path assembly
- Detection and control signal circuit board
