The Rhopoint IQ Gloss-Haze-DOI-Goniophotometer has been established as the reference instrument for measuring reflective appearance. In a single fast measurement it captures information about the gloss and texture on a sample surface. Combined gloss, haze and orange peel (DOI/RIQ values) information has made the IQ essential for controlling appearance finish in the paints and coatings sector, particularly for automotive and marine coatings. The Rhopoint IQ FLEX 20 brings this technology to a new format specifically designed for curved surfaces, small and delicate parts and In-line measurement.

Designed for curved surfaces
Conventional gloss instruments are best suited to large flat areas and test panels, as curved surfaces cause measurement errors. The small footprint of the IQ FLEX 20 makes it much more effective on curved surfaces than a conventional glossmeter; its compact size and shape also allows access to difficult to reach areas.





Easy customization for every application
The Rhopoint IQ FLEX 20 can be customized with magnetically attached adaptor plates. These can be easily interchanged for different applications:

  • Reduced measurement spot sizes (2 & 4mm) for small parts and curved surfaces.
  • Bespoke 3D printed adaptor jigs for repeatable control of small parts, buttons and controls.
  • Non-contact plates for in-line applications.
  • Alternative rubber, felt or plastic adaptors can be specified for delicate surfaces.

In-line Applications
Non-contact adaptor plates allow the measurement head to be fixed above moving products on line or robotized. USB or Bluetooth remote control allows easy integration with production

The IQ FLEX 20 Quantifies Surface Quality Problems That are Invisible to a Standard Glossmeter
The Rhopoint IQ FLEX 20 measures reflected image quality; it is the only hand held instrument that profiles how light is reflected from a surface. Glossmeters are usually used to measure the shininess of a surface but are not sensitive to common effects which reduce appearance quality.

The IQ FLEX 20 Measures
20° Gloss • RSPEC • Reflectance Haze Reflected Image Quality • Distinctness of Image • Goniophotometer Curves

Reflectance Haze - An optical effect caused by microscopic texture or residue on a surface.
Visible Symptoms: A milky finish is apparent on the surface with a loss of reflected contrast. Halos and patterns can be seen around reflections of high intensity light sources. Causes: Poor dispersion, raw material incompatibility, additive migration, vehicle quality, stoving/drying/curing conditions, polishing marks, fine scratches, ageing, oxidization, poor cleanliness/surface residue.

Reflectance Haze Compensation - The instrument compensates for reflection from within the coating for highly reflective pigments, metallic coatings and speciality pigments, allowing the haze of any painted surface to be measured.

Reflected Image Quality (RIQ) - RIQ is used to quantify effects such as orange peel and surface waviness. This new parameter gives higher resolution results compared to Distinctness of Image (DOI) measurement and better mimics human perception of surface texture, especially on high quality finishes such as automotive. Symptoms of poor RIQ: 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 - Fast measurement of all parameters. Full on-board statistics with graphical trend analysis and reporting.

Easy Batching - User definable batch names and batch sizes for quicker and more efficient reporting.

Rapid Data Transfer - Software-free data transfer. USB connection to PC instantly recognizes the device as a drive location which facilitates the quick transfer of files using Windows Explorer or similar.

Power - 20,000+ readings per charge. The instrument is rechargeable via USB/PC or mains.

Goniophotometric Curves - Different types of surface textures produce identifiably shaped reflectance profile. This goniophotometric data can be downloaded to PC for further analysis and comparison via the USB cable or Bluetooth Data Widget.
