The Rhopoint ID provides a better defined, more flexible measurement of Haze

The Rhopoint ID measures Haze by quantifying the contrast of a target graticule viewed with the material in contact or with variable airgaps.

The effect of sample-object separation is important- a material can appear fully transparent with perfect contrast at a certain distance but will completely obscure (no contrast) an object with a small increase in displacement.

At 8mm the Rhopoint ID Haze measurement directly correlates with ASTM D1003 Haze.

The Rhopoint ID directly measures Haze in a method that matches the end user application and correlates closely with the visually experience.
