Faraday's isolator device

The utility model provides a faraday's isolator device, include: polarization splitting prism is organized to the first polarization splitting prism of group, faraday's rotation device, 45 natural optically activ materials and second along the light path sets gradually, the first polarization splitting prism of group has been used for inclined to one side incident light, and the reverberation can't pass through from it, faraday's rotation device and 45 natural optically activ materials are to the rotation effect opposite direction of incident light polarization face, and are the same to the rotation effect direction of reverberation polarization face, the polarization splitting prism of second group is unanimous with the first polarization splitting prism's of group polarization face for play inclined to one side reverberation, and the incident light passes through from it. 本实用新型提供了种法拉第隔离器装置，包括：沿光路依次设置的第组偏振分光棱镜、法拉第旋光装置、45°自然旋光材料和第二组偏振分光棱镜；第组偏振分光棱镜用于起偏入射光，且反射光无法从其通过；法拉第旋光装置与45°自然旋光材料对入射光偏振面的旋转作用方向相反，对反射光偏振面的旋转
