  • Standard specifications

Bismuth silicone oxide (Bi12SiO20, BSO) crystals are highly efficient photoconductors with low dark conductivity, that allows a build-up of large photo-induced space-charges. Tremendous photoconductivity and electro-optic properties rise BSO crystals to be used for a range of applications: spatial light modulators, optical switches, phase conjugation mixers. BSO crystals are grown by modified Czochralski method and available up to 3‘‘ diameter aperture size.
