haze

Pollution control; Air pollution

A phenomenon that results in reduced visibility due to the scattering of light caused by aerosols. Haze is caused in large part by man-made air pollutants.

haze

Manufacturing; Plastic injection molding

The cloudy appearance of a material caused by light scattered from within the specimen or from its surfaces.
