Contours may be distorted and
seem less distinct. This effect,
called clarity, influences the
resolution of fine details.
Unlike haze, clarity is distance-
dependent, and deteriorates as
the distance between the
specimen and the observed object
increases (near/far transparency).
Transparency Evaluation Criteria
The appearance of a transparent
product is a function of gloss, color
and transparency. Essential criteria of
transparency are total transmittance,
haze and clarity.
Total transmittance is the ratio of
total transmitted light to incident
light. It is reduced by reflectance and
absorbance.
According to ASTM D 1003, haze is
the percentage of transmitted light
that deviates from the incident
beam by more than 2.5° on the
average. Clarity can be evaluated
at angles of less than 2.5°.
