Applied Scintillation Technologies Ltd
Applied Scintillation Technologies (AST) is a maker of imaging and detection products that utilize phosphor and scintillation technologies. More simply put, AST offers X-ray and other imaging devices that are used in the medical, dental, security, and instrumentation industries. Products include laser alignment devices, infrared digital cameras, phosphor screens, photometers, and radiometers. Founded in 1920, the company was originally called Levy West Laboratory and was an early maker of phosphors for X-ray machines. It was at one time a subsidiary of Levy Hill Group Plc, but members of AST's management (through an entity called TQ Scientific) bought the firm in 2007.
