BGO
BGO is short for bismuth germanate (Bi₄Ge₃O₁₂), a sillenite inorganic oxide crystal that is colorless, transparent and insoluble in water. Irradiation by high-energy rays such as gamma rays and X-rays, or by ions, produces green light peaking at 480nm. Its high cutoff energy, high scintillation efficiency, high energy resolution and nondeliquescent properties make BGO an excellent scintillator with important applications in high-energy physics, nuclear physics, space science, nuclear medicine, geological exploration and other industrial fields.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
