37B-Series FOG Optical Module

Product Description
This series optical module is an optical component applied toultraminiature FOG and also a special optical module that is fused and assembled by fiber-optic coils and optical devices (Y-waveguide, photodetector) in the order of gyroscope's optical path. It can replace fiber-optic coil, Y-waveguide and other separated parts for direct modular installation on the gyroscope , thus simplifying the assembly process of the FOG.
Product Features

    •   High integration
    •   Small size Light weight
    •   High reliability
