eXcelon deep-depletion CCDs

Share this on social media:

Princeton Instruments has introduced eXcelon deep-depletion CCDs and cameras for low-light, near-infrared (NIR) imaging and spectroscopy. New eXcelon deep-depletion technology provides significant improvements over standard deep-depletion technology, including reduced etaloning and higher quantum efficiency (QE) across a broader wavelength range (200 to 1,100 nm).

The CCDs, with 1,340 x 100, 1,340 x 400, 1,024 x 1,024, and 1,340 x 1,300 resolutions, are available in Princeton Instruments Pixis and Spec-10 deep-cooled, low-noise camera platforms. As well as being ideal for broad UV-NIR detection, new eXcelon deep-depletion technology is also especially well suited to low-light, NIR imaging and spectroscopy applications, including NIR Raman spectroscopy, solar wafer/cell inspection, NIR luminescence, and astronomy.

The CCDs provide excellent photon-detection capabilities across a wider spectrum, from 200 to 1,100nm, and are particularly beneficial for applications requiring enhanced sensitivity in the blue and NIR regions. In addition to delivering peak QE of greater than 95 per cent and as much as a 45 per cent increase over a broader UV-NIR wavelength range, eXcelon deep-depletion sensors offer a further reduction in etaloning.

The addition of eXcelon deep-depletion technology extends the benefits of eXcelon-enabled cameras to an even wider variety of applications in both the life sciences and physical sciences. Examples include astronomy, Raman spectroscopy, live-cell imaging, confocal imaging, and total internal reflection fluorescence (TIRF), among others.
