Rhopoint IQ - Goniophotometer

The Rhopoint IQ is a cutting-edge goniophotometer that measures gloss, haze, and DOI (Distinctness of Image) in a single reading. Using advanced reflectance profiles, this instrument allows you to fully evaluate surface appearance with just one click.

Why Choose the Rhopoint IQ?

Traditional glossmeters only measure gloss — but that is not enough to fully assess surface quality. The Rhopoint IQ glossmeter goes further, detecting visual defects that are invisible to standard instruments, like orange peel, haze, and other surface inconsistencies.

Detect and diagnose key appearance issues:

• Orange peel.
• Raw material incompatibility.
• Poor dispersion.
• Reticulation.
• Additive migration.
• Surface changes during curing, stoving, or drying.

Industries and Applications

The Rhopoint IQ is widely used in:

• Automotive and metal finishing.
• Paints, coatings, and ink manufacturing.
• Plastic and polished metal surfaces.
• Any application where a flawless, high-gloss finish is essential.

What It Measures

• Gloss (20° / 60° / 85°): Measures the amount of reflected light. Ideal for low, medium, and high gloss finishes.
• Haze: Optical scattering caused by micro-textures or residues. It produces halos around reflections, reducing visual quality.
• DOI (Distinctness of Image): Indicates how clearly an image is reflected on a surface, revealing orange peel and other textural issues.
• RSPEC: The peak gloss value measured over a very narrow angle. Useful for analyzing highly reflective surfaces.

Key Features & Benefits

• All-in-one measurement: Gloss, haze, DOI and RSPEC in under 2 seconds.
