Haze Measurement

Haze plays a critical factor in the efficiency of a solar module.  Conventional haze measurement is performed off-line, on a small sample of material, against various standards including ASTM D1003.

Dark Field Technologies has developed a revolutionary means to measure these haze levels, on-line, in real-time, on 100% of the material, not a small sample.  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.  This map can be integrated with downstream reject gates or slicing/chopping systems to ensure that only good product is shipped form the plant.
