Dark Field sells inspection tools to CIGS PV firm

Dark Field Technologies Inc of Orange, CT, USA, which provides laser and camera inspection and metrology systems for the solar thin-film plastic film, displays, glass, electronics and semiconductor industries, has won an order for multiple systems worth more than $500,000 from a top-tier manufacturer of thin-film copper indium gallium (di)selenide (CIGS) photovoltaic panels.

NxtGen Scribe 100 is an on-line, real-time, 100% solar cell scribe metrology system, which is coupled with NxtGen Wash to achieve on-line haze measurement, washer debris detection, glass defects and length/width/squareness measurement.

The NxtGen Scribe 100 metrology technology uses dark-field optics and high-speed scan cameras to inspect on-line P1, P2 and P3 scribing operations. NxtGen Wash detects edge chips/cracks and broken corners/flairs, transparent conductive oxide (TCO) coating defects and washer residue, panel warp/thickness or concentrator profile at ±15 microns. More than 500 million pixels are captured and analyzed in 3 seconds.

Each Dark Field system is custom-designed and produced for individual customers, notes president Tim Potts.
