Konica Minolta Rhopoint IQ-S 20°-60°-85°
Rhopoint IQ-S 20°-60°-85° is an innovative goniophotometer that provides key measures of surface appearance, gloss, haze and RIQ for detecting surface defects like orange peel or surface haze. Where standard gloss meters only measure gloss, the IQ-S is a cost effective solution for detection and measurement of all surface imperfections. The IQ-S is a specially designed instrument built specifically to match automotive interior gloss measurement standards. In addition IQ-S gloss measurements are fully compatible with existing Micro-TRI-gloss - S results. Dualgloss 20/60° or Trigloss 20/60/85° versions are close tolerance selected for maximum accuracy and resolution in all gloss applications.
The Rhopoint IQ-S measures
20/60/85° Gloss • Haze • Distinctness of image • Rspec • Goniophotometric curves
A measurement proportional to the amount of light reflected from a surface. Geometry: For best results the correct measurement geometry should be chosen based on the reflectance of the material: Matt Finish 85°, Mid Gloss 60°, High Gloss and Metallics 20°. Measurement Unit: GU.
The peak gloss value over a very narrow angle. Usage – RSPEC is very sensitive to small changes in texture and is used to identify subtle differences in surface smoothness. Measurement Unit: GU.
An optical effect caused by microscopic textures or residue on a surface. Visible Symptoms: Milky finish apparent on surface, loss of reflected contrast, halos and patterns seen around reflections of high intensity light sources. Specifically pertains to high gloss on materials such as metallic and mirrors. Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scratches, aging, oxidation, poor cleanliness/surface residue. Measurement Unit: LogHU.
DISTINCTNESS OF IMAGE (DOI)
A measure of how clearly a reflected image will appear in a reflective surface. Symptoms of Poor DOI: 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. Measurement Scale: 0-100, 100 is a perfect smooth surface.
REFLECTED IMAGE QUALITY (RIQ)
Same as 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. Measurement Scale: 0-100 whereas 100 represents a perfect smooth surface.
The instrument displays surface reflectance profiles 17-23°. The shape of the curve describes how the light has interacted with the surface. Sharp curves close to the specular direction indicate smooth highly reflective surfaces.
