The optical crystal with the maximum erectro-opotic(EO) effects among existing materials.
High-speed optical control is possible by making use of the large electro-optic (EO) effect.
When applied to optical scanners, it allows movement tracking in a manner that has never been possible with conventional technology.
By making use of the high EO effect (Kerr effect), it is possible to create a small-sized and high-speed optical scanner (optical polariscope), a vari-focal lens, or an efficient phase modulator (optical switch).
