Princeton Instruments has launched its emICCD technology, available in its PI-MAX 4 camera platform.

The camera combines the advantages of ultrashort, subnanosecond exposure times and the benefits of linear gain and high quantum efficiency to provide single-photon sensitivity and quantitative performance for scientific imaging and spectroscopy applications.

'Traditional intensified cameras, the workhorses of ultrashort, time-resolved applications, are limited by nonlinearity due to microchannel plate [MCP] saturation as well as an inability to distinguish single photons. Alternatively, EMCCD cameras, which have become the main tools for low-light applications, lack ultrashort [i.e., psec to μsec] gating capabilities,' said Ravi Guntupalli, vice president of sales and marketing at Princeton Instruments.
