DOI / IQ Meter / Orange Peel / Goniophotometer

Model Number: IQ-20/60 & IQ-20/60/85

The Rhopoint IQ quantifies surface quality problems that are invisible to a standard glossmeter and profiles how light is reflected from a surface. This incredibly advanced instrument measures: HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC In practice, these terms mean: Haze: An optical effect caused by microscopic textures or residue on a surface. RIQ : Used to quantify effects such as orange peel and surface waviness. This new parameter gives higher resolution results compared to Distinctness of Image (DOI) measurement and better mimics human perception of surface texture, especially on high quality finishes such as automotive paint finish. 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.
