The classic instrumentation for collecting high quality single crystal diffraction data for more than few ten years has been the four-circle single crystal diffractometer. Althoughmany improvements occurred over that time span in faster computing and better software algorithms for automatically indexing the unit cell, for Bravais lattice transformation, forspace group determination, and for structure solution and refinement, the basic mechanical design of the diffractometer remained largely unchanged.By 1990 research was underway at our company to attempt to extend the benefits of two-dimensional detectors to ‘small molecule’ applications, and we looked specifically at the alternative of a solid-state detector incorporating a Charge-Coupled Device, or CCD. These were already being used in astronomy and other imaging applications. After a number of prototypes and extensive software development, the first commercial CCD system for single crystal diffraction, SMART, was announced by Bruker AXS (as Siemens) in 1993 at the Pittsburgh Diffraction Conference.
