DOI glossmeter / haze / three-angle / portable

The IQ instruments measures 20/60 or 20/60/85° Gloss Haze (reflection) RIQ, DOI RSPEC Goniophotometric curves

- GLOSS
A measurement proportional to the amount of light reflected from a surface. PEAK GLOSS

- VALUE (RSPEC)
The peak gloss value over a very narrow angle.

- REFLECTANCE HAZE
An optical effect caused by microscopic textures or residue on a surface.

- DISTINCTNESS OF IMAGE (DOI)
A measure of how clearly a reflected image will appear in a reflective surface.

- REFLECTED IMAGE QUALITY (RIQ)
Like DOI, Reflected Image Quality (RIQ) is used to detect Orange peel effects. However, the RIQ value provides high resolution results with better correlation to the human perception of surface textures, especially on high quality surfaces such as automotive paints.
