31. Article: NIR Trends: Photoluminescence Inspection Of Photovoltaics With SWIR Imaging 11/9/2009

    Contactless machine-vision inspection using photoluminescence (PL) imaging with shortwave infrared (SWIR) cameras can help solar cell producers improve both efficiency and quality of their photovoltaic products. Inspection of silicon bulk ingots, sliced wafers, processed layers, and complete photovoltaic cells is possible with SWIR imaging.

33. NIR Trends: Maximizing Solar Cell Yield And Efficiency With Machine Vision 7/23/2009

    As the first decade of the 21st century draws to a close, the easy oil has been harvested and each new barrel will be more expensive to pull from the ground. With world demand for energy still expanding, and the impact of burning carbon based fuels burdening the atmosphere, the development and installation of efficient renewable energy sources has become crucial.

    Manufacturers have used cameras to monitor their processes since the first industrial cameras were made available. What do you do when there are no visible differences to distinguish good product from bad?

38. Technical Article: What You Should Ask Before Investing In A Shortwave Infrared (SWIR) Lens 1/30/2009

    The military and industrial communities are investigating shortwave infrared (SWIR) technology for new and improved imaging solutions for a variety of challenging applications. Indium gallium arsenide (InGaAs) is a material often used for SWIR imaging due to its high quantum efficiency and low dark current. This advanced InGaAs material makes these detectors the most sensitive imagers that operate in the shortwave IR wavelength range at any given temperature. By MARC HANSEN

40. Article: NIR Trends: Penetrating The Haze Of Scattered Light 10/24/2008
    In the July column of NIR Trends, we discussed the interaction of electromagnetic waves with materials they encounter, and how the interaction can tell us a great deal about the chemistry and physical makeup of those materials. This is the basis of most forms of spectroscopy. We went on to describe the impact NIR spectroscopy is having on our lives, particularly in biomedical imaging. In that context, light scattering was mentioned as a complication. This column will expand on the topic of light scattering and its impact on imaging with cameras at various wavelengths. Illustrations will compare images taken between visible and the shortwave infrared SWIR in haze, dust, and smoky conditions.
