Princeton Instruments has unveiled its 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 pixel resolutions of 1340 x 100, 1340 x 400, 1024 x 1024 and 1340 x 1300, are available in the company’s Pixis and Spec-10 deep-cooled, low-noise camera platforms. The sensors deliver peak quantum efficiency of >95% and as much as a 45% increase over a broader UV-NIR wavelength range. They are suitable for use in live-cell imaging, confocal imaging, total internal reflection fluorescence, Förster resonance energy transfer and superresolution techniques, including stochastic optical reconstruction microscopy and photoactivated localization microscopy.
