PRODUCTS ROUND-UP INGAAS CAMERA WITH MULTIPLE APPLICATIONS
NIR CAMERA FOR INSPECTION
Flir ATS has launched its SC2600 near infrared (NIR) camera for the research and science community. With its low noise and highly sensitive 640 × 512 InGaAs sensor, the affordable SC2600 NIR camera is ideal for automation, research and science applications.
The SC2600 combines excellent sensitivity throughout the spectral range 0.9-1.7µm and high resolution, enabling detection of small targets and accurate, reliable measurements. The compact size and light weight of the camera enhances the flexibility of operation even in space-restricted environments. Features include independent analogue and digital (Gigabit Ethernet) video outputs, external frame synchronisation, video windowing, and independent data streams. The camera delivers ready to use, sharp images for applications as diverse as hyperspectral imaging, solar cell inspection, laser profiling, medical research, water or ice detection, silicon wafer processing, skin damage evaluation, phenomenology and many others.

22 PHOTOVOLTAICS 2012
Princeton Instruments has released its PIoNIR:640 camera that uses a deep-cooled indium gallium arsenide (InGaAs) focal plane array. The PIoNIR is designed for use in low-light near infrared (NIR) or shortwave infrared (SWIR) imaging and spectroscopy applications that require high sensitivity from 0.9µm to 1.7µm. PIoNIR applications range from nanotube fluorescence imaging to photovoltaic (PV) inspection. Previous InGaAs cameras required liquid nitrogen to achieve deep cooling but vacuum technology developed at Princeton means the PIoNIR:640 can reach minus 90°C using thermoelectric cooling. The PIoNIR:640 uses a 640 x 512 InGaAs array with a peak quantum efficiency greater than 80 per cent with the thermoelectric cooling. It also has low-noise readout electronics to deliver the highest possible sensitivity.
Ravi Guntupalli, product manager for Princeton Instruments’ imaging group said: ‘The PIoNIR sets a new performance benchmark, enabling novel research and industrial applications in diverse life and physical science areas
VISION ENSURES SMOOTH SOLAR CELL
Isra Solar Vision has released Solarscan-Bevel for the inspection of solar cells after printing and before firing. This enables manufacturers to clear compound spots on cell edges that could lead to short-circuits in all following cells. In addition, the inspection system can detect
when production meshes have to be exchanged.
Cell edges are the most critical areas for compound spots, because the pressure exerted on the mesh is extremely high. Being applied in every production line right after printing and before the firing process, Solarscan-
Bevel enables manufacturers to optimise their process and to avoid non-reparable defects. Using the inspection system, material with short-circuits is not passed on to higher processing steps and therefore defective cells can be avoided and resources saved.

such as semiconductor failure inspection, singlet oxygen imaging, photoluminescence imaging of PV materials, NIR fluorescence and absorbance, and deep tissue imaging.’

VISION SENSOR FOR WAFER ALIGNMENT
Sick has launched a vision sensor in the Inspector family, the PI50. The vision sensor allows users to build their own interfaces easily, as well as operate it from any computer or operator panel with a standard web browser.
The Inspector PI50 is ideal for applications such as solar wafer alignment and damage detection, fiducial alignment in electronics, calibrated robot guidance in automotive, positioning control
in commercial goods production and integrated quality control in packaging machines.
The vision sensor contains an expanded toolbox for object location and positioning based on a taught-in pattern, free-form and line/polygon object shapes. In addition to the positioning tools, it provides tools for quality inspection such as blob, pattern, edge and pixel counting inspection. A new calibration feature
supports image translations to ensure that results are exactly aligned with the external machine environment. It also provides reliable images even in tight and tilted setups where the image could otherwise be distorted. The device is available in a white or infrared ring light option. It supports extended results and control handling over EtherNet/IP and TCP/IP.
