Faraday Rotator Glass
- SUMITA’s Faraday rotator glass is a glass material for a faraday rotator optical element, which is ideal for isolators for visible light and faraday cell polarimeters.
- SUMITA provides two types of faraday rotator glasses - VL5000 and VR1000. VL5000 is a paramagnetic glass with a high rotational characteristic, and VR1000 is a diamagnetic glass, suitable for use of lead glass replacement.
- RoHS: Compliant
