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: 20/60° GLOSS • HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC In practice, these terms mean: Gloss: A measurement proportional to the amount of light reflected from a surface measured at 20° (high gloss) and 60° (mid gloss)

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.

The Ultimate Glossmeter Upgrade

THE RHOPOINT IQ QUANTIFIES SURFACE QUALITY PROBLEMS THAT ARE INVISIBLE TO A STANDARD GLOSSMETER The Rhopoint IQ measures reflected image quality; it is the only hand held instrument that profiles how light is reflected from a surface. Glossmeters are usually used to measure the “shininess” of a surface but are not sensitive to common effects which reduce appearance quality.

Gloss

A measurement proportional to the amount of light reflected from a surface. Geometry: The correct measurement geometry should be used according to the sample finish – matt: 85°, mid gloss: 60°, high gloss: 20°.

RSPEC

The peak gloss measured over a very narrow angle. Usage: It is very sensitive to surface texture and can be used to identify subtle differences in smooth surfaces.

Reflective Haze

An optical effect caused by microscopic texture or residue on a surface. Visible Symptoms: A milky finish is apparent on the surface with a loss of reflected contrast. Halos and patterns can be seen around reflections of high intensity light sources. Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scratches, ageing, oxidisation, poor cleanliness/surface residue.

Reflective Haze Compensation

The instrument compensates for reflection from within the coating for highly reflective pigments, metallic coatings and speciality pigments, allowing the haze of any painted surface to be measured

Reflected Image Quality (RIQ)

RIQ is 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. Symptoms of Poor RIQ: Orange peel, brush marks, waviness or other structures visible on the surface. Reflected images are distorted. Causes: Application problems, incorrect coating flow, coating viscosity too high/low, sag or flow of coating before curing, incorrect particle size/distribution, overspray, improper flash/recoat time, inter coat compatibility, incorrect cure times and cure temperature.

Distictness Of Image (DOI)

A measure of how clearly a reflected image will appear in a reflective surface.
