Orange peel glossmeter Rhopoint AIDO

DOIhazewith data output

Short description

• Inline sensor for continuous surface appearance measurement
• Measures 60° gloss, reflectance haze (Log H / Log HC), Distinctness of Image (DOI) and RSPEC in real time
• Fixed 60 mm working distance for stable inline operation
• Non-contact measurement for hot, freshly coated or delicate surfaces
• High-speed capture up to 10 measurements per second
• Integrated air purge and optical protection for coating environments

Continuous appearance assurance for production lines
AIDO enables a move from intermittent sampling and laboratory checks to continuous inline appearance assurance. Mounted above moving webs, panels or finished components, the sensor provides immediate visibility of changes in gloss, haze, image clarity and peak specular reflection so production teams can react while material remains on the line.

Built for inline production environments
AIDO is engineered for fully non-contact operation above hot, freshly coated or delicate surfaces. A fixed 60 mm distance-to-surface ensures stable measurement on unguided webs, variable-thickness panels and conveyors. An integrated air purge protects the optical path from dust, vapours and contamination common in coating lines.

Measuring appearance, not just gloss
Surfaces with identical gloss values can appear different due to haze, texture or reflected-image distortion. AIDO measures multiple complementary appearance parameters that together describe how a surface is perceived by the human eye, revealing changes invisible to gloss-only sensors.

What the AIDO inline sensor measures
By combining 60° gloss, reflectance haze (Log H and Log HC), Distinctness of Image (DOI) and RSPEC in a single non-contact inline system, AIDO provides a perceptually relevant, real-time assessment of surface appearance.

Key appearance parameters (descriptions)

• 60° gloss — Measurement proportional to the amount of light reflected at 60° geometry (reference geometry suitable across gloss levels).
• Reflectance haze (Log H / Log HC) — Quantifies diffuse scatter from microscopic texture, residues or coating structure; Log HC provides correction for metallic and special-effect coatings.
• Distinctness of Image (DOI) — Measures reflected image sharpness; sensitive to orange peel, waviness and micro-roughness that reduce perceived quality without changing gloss.
• RSPEC — Measures peak specular reflection over a narrow angular interval around the specular angle; highly sensitive to fine surface texture differences and smoothness.

High-speed operation and system integration
AIDO supports high-speed measurement up to 10 captures per second, delivering dense coverage on fast-moving production lines. Measurement data is available instantly via a REST API for integration with PLCs, MES and quality platforms. Sensor management, configuration, calibration control, health monitoring and data access are provided through the Rhopoint Appearance Elements platform.

Applications and suitability
Designed for inline monitoring of moving webs, panels and finished components; suitable for hot, coated or delicate surfaces and environments requiring non-contact, high-speed monitoring. Integrated air purge and optical protection make AIDO appropriate for coating lines and demanding manufacturing conditions.
