The Rhopoint IQ quantifies surface quality problems that are invisible to a standard glossmeter. This incredibly advanced instrument measures:
20/60/85° GLOSS • HAZE • DISTINCTNESS OF IMAGE • RSPEC
In practice, these terms mean:
Gloss: Surface shininess
Haze: An optical effect caused by microscopic textures or residue on a surface.
DOI: A measure of how clearly a reflected image will appear in a reflective surface.
RSPEC: The peak gloss value over a very narrow angle.
DOI results can be used to quantify application problems such as orange peel.
Orange peel and other textures can be directly measured using DOI, measuring this value can also tell us about flow and levelling of samples in the laboratory

The Rhopoint IQ is unique as it supplies surface gloss and texture information in one quick, simple and easy to understand measurement. Gloss, Distinctness of Image, Haze and RSPEC measurements are taken in a single reading at 20° or 60° .
Whilst glossmeters are widely used throughout industry to assess the reflective qualities of products, gloss information alone is limited as it tells us how much light is reflected, but nothing about the imaging forming qualities of a surface.
Phenomena such orange peel, haze effects and polishing marks distort reflections in a surface, seriously reducing visual appearance but cannot be measured with traditional glossmeter. This means two surfaces which have very different reflective properties often have exactly the same gloss value.
The DOI, Haze and RSPEC values measured by the Rhopoint IQ allow the user to quantify and control the surface textures that reduce the perceived quality of manufactured products.
