Transmittance Options
The Datacolor 850/550 includes an option to measure the transmission properties of
transparent and translucent samples. The 850/550 can measure the “regular” transmittance
of transparent solid and liquid samples, as well as the “total” and “diffuse” transmittance of
translucent samples. The Datacolor 850/550 can also be used to perform the following
evaluations:

Haze evaluations, in compliance with ASTM D1003 Standard Test Method for
Haze and Luminous Transmittance of Transparent Plastics, for materials that
exhibit slight light scattering.

APHA evaluation, which measure the yellowness of liquids.
The transmission compartment of the Datacolor 850/550 is large enough to allow the
operator to easily insert and remove samples. It has been fitted with a spill tray in the event
of minor spillage of liquid samples.
