Princeton Instruments (Trenton, NJ) has introduced its SOPHIA series of cameras for low-light-level scientific applications. The cameras feature Princeton Instruments’ proprietary new ArcTec™ thermoelectric cooling technology. Applications include astronomy, in vivo small-animal imaging, chemiluminescence, soft x-ray imaging, and spectroscopy.

Based on a 2k × 2k sensor format, SOPHIA’s multiple-port, back-illuminated CCDs leverage patented Princeton Instruments eXcelon® technology. SOPHIA’s 30.7 × 30.7 mm photosensitive array features 15 μm x 15 μm pixels.

ArcTec cooling technology minimizes dark noise by cooling the CCD to less than -90°C. eXcelon sensor technology reduces unwanted fringes in the near-infrared region. The SOPHIA products use the USB 3.0 data interface and multiple-port readout capabilities up to 16 MHz.

New SOPHIA cameras are supported by 64-bit LightField® imaging and spectroscopy software. One of the camera variants (i.e., the SOPHIA-XO) uses no antireflective coatings and employs an open-nose design in order to facilitate soft X-ray detection.
