OverviewThe Rhopoint IQ Flex 20 is a portable instrument that quantifies surface appearance defects (gloss, reflectance haze and reflected image quality) on small, curved or hard-to-reach parts. It extends Rhopoint's IQ technology to applications where conventional glossmeters cannot access the correct reflection angle, while producing results compatible with standard IQ datasets.
Key capabilities- Accurate 20° geometry measurements adapted for high-gloss finishes on small and curved surfaces.
- Simultaneous output of 20° Gloss, Reflectance Haze, Reflected Image Quality (RIQ) and Distinctness of Image (DOI).
- Automatic peak detection and virtual sensor adjustment for curved or textured substrates.
- Magnetic, interchangeable adaptors including reduced spot sizes down to ~2 mm and bespoke 3D-printed jigs for repeatable positioning.
What the IQ Flex 20 measures- 20° Gloss (high gloss)
- Reflectance Haze
- Reflected Image Quality (RIQ)
- Distinctness of Image (DOI)
- Goniophotometric curves
- RSPEC (peak specular reflectance)
Technology & measurement methodThe unit uses a high-resolution 512-element linear diode array to profile reflected light across an angular range (~14°–27°). Software selects array elements matching 20° tolerances and computes gloss and haze. For curved or textured components the instrument detects the reflected peak and applies virtual alignment, ensuring measurements correspond to the correct gloss angle. For metallic or high-reflectance coatings a diffuse/reflectance compensation prevents inflated haze readings due to internal reflection.
Interchangeable adaptors- Magnetically mounted plates for repeatable positioning on irregular parts.
- Reduced measurement spot sizes (examples: ~6 mm, ~4 mm, ~2 mm) for small features.
- Custom 3D-printed adaptor jigs available from CAD models for complex geometries.
- Adaptors for convex, concave and multi-curvature surfaces.
User interface & features- Full-colour rotatable display (landscape/portrait) with clear numeric and graphical outputs.
- Touch-sensitive controls and a single measurement button for rapid operation.
- Automatic batch sequences, user-definable batch names and onboard statistics with graphs.
- Fast simultaneous calculation of all parameters with date/time stamping and exportable results.
ApplicationsDesigned for quality control of appearance-sensitive components: automotive exterior and interior panels, consumer electronics housings, small painted or polished plastic and metal parts, furniture surfaces, polished stone and other curved or miniature components.
