Original Press Release:


An established instrument for measuring reference of reflective appearance like Gloss - Haze – Distinctiveness of Image (DOI), & Goniophotometer Curves

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.

Previously only available for measuring flat surfaces, this technology is now available in a new format specifically designed for curved surfaces and small & delicate parts.


• Designed for measurement of small & curved surfaces

• Easy results batching with user definable names

• Bluetooth compatibility for transmitting data

• Full on-board statistics (max, min, mean, S.D.) & graphs

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

– Interchangeable magnetic adaptors allow reduced measurement spot sizes down to 4mm or 2mm

– Bespoke 3D printed adaptor jigs for repeatable control of small parts, buttons and controls
