ABSTRACT:
An apparatus and method for measuring and analyzing light transmittance through containers is provided. A system is disclosed in which a light probe is insertable into a container in order to measure light transmittance through portions of the container wall. The light probe is connected to a spectrophotometer which analyzes the light transmitted through the container wall. Light transmittance is measured over a series of light wavelengths in order to accurately predict the ability of the container to protect its contents from the detrimental effects of light. In addition, the container may be tested for light transmittance at several locations. The measured light transmittance of each location may be weighted differently in order to compensate for the anticipated exposure to light of the particular location.
