TRENTON, N.J., Feb. 23, 2016 — Princeton Instruments has introduced the SOPHIA series of ultralow-noise cameras for low-light-level scientific applications. The cameras feature proprietary ArcTec thermoelectric cooling technology, which minimizes dark noise by cooling the CCD to less than −90 °C using only air assist. Applications include astronomy, in vivo small-animal imaging, chemiluminescence, soft x-ray imaging and spectroscopy. The camera’s 30.7 × 30.7-mm photosensitive array with 15 x 15-μm pixels detects 23 percent more photons per pixel than equivalent back-illuminated sensors that have 13.5 × 13.5-μm pixels. EXcelon sensor technology broadens sensitivity over a wider wavelength range and reduces unwanted fringes in the near-infrared region, further improving signal-to-noise ratio. The camera features USB3 data interface and multiple-port readout capabilities up to 16 MHz.
