NIR InGaAs camera from Princeton Instruments for SWIR imaging

March 12, 2012
The PIoNIR:640 scientific-grade camera utilizes a 640 × 512 pixel indium gallium arsenide (InGaAs) focal-plane array with thermoelectric cooling down to -90°C.

The PIoNIR:640 scientific-grade camera utilizes a 640 × 512 pixel indium gallium arsenide (InGaAs) focal-plane array with thermoelectric cooling down to -90°C. It is specifically designed for use in low-light NIR or SWIR imaging and spectroscopy applications that require high sensitivity from 0.9 to 1.7 μm. Applications range from nanotube fluorescence imaging to photovoltaic (PV) inspection.

Deep-Cooled, 640 x 512 InGaAs Camera Engineered for Advanced Low-Light NIR/SWIR Applications in Life and Physical Sciences

Trenton, New Jersey, December 19, 2011 — Princeton Instruments is pleased to introduce the PIoNIR:640, the world’s first scientific-grade camera to utilize a deep-cooled InGaAs (indium gallium arsenide) focal plane array. The PIoNIR™ is specifically designed for use in challenging low-light near infrared (NIR) or shortwave infrared (SWIR) imaging and spectroscopy applications that require high sensitivity from 0.9 µm to 1.7 µm. PIoNIR applications range from cutting-edge nanotube fluorescence imaging to photovoltaic (PV) inspection.

“The PIoNIR:640 is a very unique NIR/SWIR camera in today’s market. It combines the advantages of the latest-generation 640 x 512 InGaAs array [peak quantum efficiency: >80%] with thermoelectric cooling [down to -90°C] and low-noise readout electronics to deliver the highest possible sensitivity in this important wavelength range,” notes Ravi Guntupalli, product manager for Princeton Instruments’ Imaging Group. “The PIoNIR sets a new performance benchmark, enabling novel research and industrial applications in diverse life and physical science areas such as semiconductor failure inspection, singlet oxygen imaging, PL [photoluminescence] imaging of PV materials, NIR fluorescence and absorbance, and deep tissue imaging.”

Previous-generation InGaAs cameras required liquid nitrogen to achieve deep cooling but thanks to state-of-the-art vacuum technology developed at Princeton Instruments the new PIoNIR:640 reaches temperatures as low as -90°C using convenient, maintenance-free thermoelectric cooling. As a result, unwanted thermal noise is minimized to achieve the best possible signal-to-noise ratio. The camera offers either built-in air or liquid cooling, or a combination of the two, for use in thermal- and vibration-sensitive environments.

The PIoNIR:640 also features a Gigabit Ethernet (GigE) data interface for remote operation from up to 50 meters away and delivers a maximum frame rate of 110 frames per second at full resolution.

The new camera is available with the latest Princeton Instruments LightField™ data acquisition software, which affords complete control over all PIoNIR:640 hardware features via an exceptionally intuitive user interface. LightField provides automatic defect correction, exposure control up to minutes, and a host of innovative functions for easy capture and export of imaging and spectral data. The PIoNIR:640 can be integrated into OEM systems using the PICAM™ SDK, a free software development kit from Princeton Instruments.
