TRENTON, N.J., Sept. 24, 2010 — Princeton Instruments has introduced eXcelon deep-depletion CCDs and cameras for low-light, near-infrared imaging and spectroscopy. Improvements over standard deep-depletion technology include reduced etaloning and higher quantum efficiency across a broader wavelength range from 200 to 1100 nm.

The new CCDs, with 1340 × 100-, 1340 × 400-, 1024 × 1024 and 1340 × 1300-pixel resolutions, are available in the company’s Pixis and Spec-10 deep-cooled, low-noise camera platforms.

Suitable for broad UV-NIR detection and for NIR Raman spectroscopy, solar wafer/cell inspection, NIR luminescence and astronomy, the back-illuminated CCDs provide good photon-detection capabilities. They are beneficial for applications requiring enhanced sensitivity in the blue and NIR regions. The sensors deliver peak quantum efficiency of >95% and as much as a 45% increase over a broader UV-NIR wavelength range.

With the new technology, the cameras are suitable for use in live-cell imaging, confocal imaging, total internal reflection fluorescence, Förster resonance energy transfer, Bose-Einstein condensate, and super-resolution techniques such as stochastic optical reconstruction microscopy and photoactivated localization microscopy.

The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
Bose-Einstein condensate
A group of atoms that have been cooled to the point that they have minimum motion and share the same, lowest possible quantum state.
solar cell
A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
