Rhopoint IQFresh reflection fog shadow tester

Rhopoint IQFresh Imaging Fog Shadow InstrumentQuantify the quality issues of surfaces that cannot be measured by a standard glossiness meter, and analyze how light reflects off the surface. Capable of measuring:

•20/60/85°gloss

•peak reflectivity

•Reflection fog shadow

•RIQimaging quality

•DOIdoi

•Angular photometric curve

1. gloss

. Proportional quantification of the light intensity reflected from the surface of an object.

Angle selection: In order to obtain good measurement results, it is necessary to base on

Choosing the correct measurement angle for the reflection coefficient of an object: the use of sub light

85⁰Used for medium gloss60⁰Used for high gloss and metallic colors20⁰The test

Measure angle.

2. peak reflectivity

Peak glossiness measured at a very narrow angle.

application:Peak reflectivity is highly sensitive to surface texture and can be used for recognition

Don't smooth out the subtle differences on the surface.

3. doi(DOI)

Measure the clarity of a reflected image on a reflective surface.

Orange peel will significantly reduce the appearance quality without affecting the gloss reading. this

The measurement results of the two test panels are the same as those of the standard glossiness meter. have

RIQ/DOIMeasurement functionRhopoint IQIt is possible to quantify the differences between them.

4. imaging qualityRIQ

RIQUsed to quantify the effects of orange peel and surface waviness. Regarding imaging quality（DOI）

Compared to measurement, this new parameter can provide higher resolution results and better performance

Simulate human perception of surface textures, especially for high-quality finishes such as cars

Up there.

imaging qualityRIQAdverse results: orange peel, paint marks, ripples or other

Visible structure. Causing distortion of the reflected image.

cause:Application issues, incorrect coating flow, high coating viscosity/Too low,

Before curing, the coating may have dents or flow, and the particle size may vary/Incorrect distribution, excessive spraying, baking

paint/Incorrect recoating time, compatibility between coatings, curing time and temperature

Incorrect, etc.

5. Reflection fog shadow

An optical effect caused by microscopic textures or residues on the surface.

symptom:There are obvious emulsions on the surface, loss of reflection contrast, and haze

Images can be seen in the reflection images of high-intensity light sources.

cause:Poor dispersibility, incompatible raw materials, migration of additives, and poor substrate quality

Quantity and baking/dry/Curing conditions, polishing marks, small scratches, aging

Oxidation and poor cleanliness/Surface residues, etc.

The haze index is a common issue encountered in spraying and polishing materials. Surface haze causes

The reflected image presents a blurry form.Rhopoint IQCan directly measure the parameter

Numerical value.

Reflection fog compensation

This instrument can compensate for high reflectivity pigments, metal coatings, and special pigment coatings inside

The reflection can be used to measure the haze of any painted surface.
