Ravi Guntupalli: Hi, I'm Ravi Guntupalli, product manager at Princeton Instruments, the Imaging and X-ray Camera Division. Princeton Instruments is the world leader in low-light level detection, imaging and spectroscopy. We provide CCDs, EMCCDs, ICCDs and InGaAs cameras for the scientific community.

Today, we are launching PIoNIR Deep-Cooled InGaAas Focal Plane Array Detector at the 2012 SPIE Photonics West Conference. We will be talking about the salient features of PIoNIR.

PIoNIR is a 640 by 512 Indium gallium arsenide, commonly known as InGaAs, focal plane array detector, cooled down to minus 90 degree Celsius using thermoelectric cooling technology. So you do not have to use liquid nitrogen to achieve low dark currents possible otherwise. The camera also has the flexibility used to external liquid circulation for vibration-sensitive environments. The sensor provides very good sensitivity because it has created 80% quantum efficiency over most of the wavelength range of 0.9 microns to 1.7 microns.

The camera is expressly designed for low light NIR imaging and spectroscopy applications such as oxygen imaging, fluorescence from single-wire carbon nanotubes, photoluminescence imaging of solar cells. So the camera is capable of detecting the lowest levels of NIR light. So we're getting a great response from researchers worldwide for PIoNIR 640.
