Princeton Instruments (PI), established in 1981, is the world's largest manufacturer of scientific, cooled CCD cameras for imaging and spectroscopy applications. All PI cameras are fully integrated with all the required controls and computer interface electronics. We also support the most popular computer platforms, such as PC, Macintosh, Sun Microsystems, and SGI Workstations.

At the 6th International Conference on Biophysics and Synchrotron Radiation, Princeton Instruments will display cameras for x-ray powder diffraction and crystallography. These high resolution, high sensitivity cameras are supported by most of the popular computer platforms. PI will also exhibit their cooled CCD cameras, sensitive enough to use for photon counting and detecting x-rays from less than 30 eV to 60 KeV and higher.
