tEchnology proDucts cameras and imaging cameras for spectroscopy


Multispectral imaging camera the Spectrocam multispectral imaging (MSI) camera is now available from ocean thin Films (otF) in a new development platform that combines a scientific-grade ccD array with a precision rotating optical filter wheel. Applications include water quality measurements, product screening, machine vision, medical imaging, surveillance and authentication. Spectrocam complements single-point


spectroscopy by adding another dimension to spectral measurements. With a single-point spectrometer, users can analyse spectral differences from sample to sample and then, by selecting discrete filters in and around spectral areas with the most significant differences, use Spectrocam to create an image that shows vivid contrast between the samples. At the heart of the Spectrocam is a wideband


ccD that is responsive from the visible through near infrared spectrum. the system's precision filter wheel and optics can be customised for a variety of applications. Image speed is 20fps at full resolution, and the standard F-mount configuration accommodates a range of lens choices, focal lengths and fields of view. each system includes a lens, eight standard interchangeable filters and software. otF collaborated with miniature spectroscopy


provider, ocean optics, to create this suite of tools, making multispectral imaging accessible to everybody, from university researchers to high volume oeM equipment makers. the interchangeable optical filters and continuously rotating filter wheel overcome many of the shortcomings that prismatic MSI systems face. With interchangeable filters, users can try many filter options to narrow in on the best contrast, greatly reducing development time and allowing users to bring products to market faster. the Spectrocam platform is easily integrated


into a variety of oeM systems and can be modified to meet specific mechanical and environmental needs. www.oceanthinfilms.com


Vision solution for solar use


Machine vision company Isra has announced its Solar Vision 3D technology for surface inspection and geometrical gauging at the printing process stage. In addition to the existing inspection and measuring functions of Isra's Solarscan front print and Solarscan rear print systems, the new 3D option allows the detection of splinters and other height relevant structural defects. cell manufacturers benefit directly from


implementation of the new inspection technology through significantly higher machine uptimes and reduced cell breakage. In total, Isra says, this

Princeton Instruments has introduced its PyLoN series of controller-less, cryogenically-cooled ccD cameras, designed for quantitative spectroscopy applications that demand the highest possible sensitivity. the first commercially available models in the new series are the PyLoN:100 and PyLoN:400, dual-amplifier cameras utilising 1,340 x 100 and 1,340 x 400 sensors, respectively. Soon-to-be-introduced models include the dual-amplifier PyLoN: 2K and the single-amplifier PyLoN: 256. In creating the new PyLoN


platform, Princeton Instruments redesigned its industry-leading Spec-10 family of cameras to remove the external controller, increasing experimental flexibility while further improving the ultra-low- noise electronics. Liquid nitrogen cooling in the new cameras virtually eliminates dark current, and indium metal seals enhance vacuum longevity. binning noise has been further reduced from the


nir camera for r&D applications


Flir Advanced thermal Solutions has developed a state-of-the-art, multi-spectral, near infrared camera for high-end r&D applications. the Sc7100 NIr camera is designed to


satisfy the requirements of a wide range of science and research applications. It is a fully integrated camera offering coverage of the spectral range of 0.4-1.7µm, and combines high performance thermal imaging and non-contact temperature measurements with superior data acquisition capabilities. While most competitive NIr cameras are


simply thermal imagers, the Sc7100-NIr provides accurate, non-contact temperature measurements. the camera is able to be


already low levels in PI’s Spec-10 platform. the ccDs used in the PyLoN:100 and PyLoN:400 cameras each feature 20 x 20µm pixels, offering researchers an optimal combination of high resolution and wide dynamic range. Select PyLoN cameras also feature Princeton Instruments’ eXcelon technology, which delivers the highest available sensitivity in the UV and NIr while suppressing the etaloning that occurs in standard back-illuminated ccDs. the PyLoN platform delivers


analogue-to-digital conversion (ADc) rates of up to 4MHz, with digital bias stabilisation and correlated double sampling for decreased read noise and improved


linearity. Kinetics mode allows microsecond- resolved kinetic spectral acquisition, and custom sensor mode increases control over the camera readout, enabling spectral rates in excess of 1,000 frames per second. www.princetoninstruments.com


calibrated for temperatures up to 3,000°c. All required image processing electronics are embedded in the camera to deliver sharp, ready-to-use images. other capabilities include high frame rates, flexible integration times, lock-in signal processing and spectral filtering. the camera can be easily connected to a standard Pc or laptop computer through its plug-and- play camlink or Gige digital interfaces. the Sc7100 NIr camera


will be of great benefit in scientific research, spectroscopic imaging, astronomy, water or ice detection, laser profiling, medical procedures, solar cell inspection, silicon wafer processing, and many manufacturing applications. www.flir.com


detection and classification of height related defects, such as splinters or particles. And a significant increase of measurement accuracy, such as for wafer bow gauging. these new features, in combination with the


enables an increase of high-quality yield and the reduction of manufacturing costs, because 100 per cent inspection is carried out. In addition to the two-dimensional surface


images, 3D inspection provides important additional information for structure and topography. the result for print inspection is the


existing inspection functions, allow for production quality and a secure print process. the Solarscan systems with the 3D option support the latest production technologies such as 'metal wrap through'. As a result, cell manufacturers no longer have to fear the increasing risk of cell breakage. the return on investment is under four months. www.isravision.com/
