BGO is a novel scintillation crystal, widely used as a scintillator for x-ray computerized tomography (XCT), positron CT (PCT), electromagnetic shower calorimeter and oil well logging. BGO features high stopping power and high photo peak efficiency, is non-hygroscopic, has low after glow, and is easy to machine to any size required. Boules up to 76 mm dia. 150 mm long. 

Also available BiGeO20piezoelectric crystal.

BSO has properties of piezoelectric, photoconductive, electro-optic crystals. Applications include image amplifiers, matrix inversion, beam combining, to mention a few. 

BSO is available for modulator applications, 50 mm diameter and 100 mm long
