Dark Field Technologies Introduces NxtGen™ Haze

Haze measurement is critical for many applications: TCO on glass, filler density in plastic film, and more.  Conventional haze measurement is performed off-line, on a small sample of material, against various standards including ASTM D1003.  Manufacturers must make a quality judgment based on an insignificant amount of product.  Dark Field Technologies has developed a revolutionary means to measure these haze levels, on-line, real-time, 100%.   The Dark Field  NxtGen™  Haze system employs proprietary optics and processing modules that allow the user to set a target haze level and control limits.  The NxtGen™ Haze system generates a “haze map” which shows the haze levels of the glass or film in a grid pattern.  Should the control limits be breached, the deviant area of the product is shown as “red” on the haze map and the system generates an alarm.  The haze map is stored in a data base for recall at a later time and this map can be integrated with downstream reject gates or slicing/chopping systems to ensure that only good product is shipped from the plant.
