Rhopoint IQ Flex 20° Goniophotometer

Description

The Rhopoint IQ Flex 20 quantifies surface quality problems such as orange and peel and haze that are invisible to a standard glossmeter and profiles how light is reflected from a surface. 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. This incredibly advanced instrument measures: 20° GLOSS • HAZE• REFLECTED IMAGE QUALITY (RIQ) • DISTINCTNESS OF IMAGE (DOI) • RSPEC

In practice, these terms mean:

Gloss: A measurement proportional to the amount of light reflected from a surface measured at 20° (high gloss)

Haze: An optical effect caused by microscopic textures or residue on a surface.

RIQ : 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 paint finish.
Compact measuring head enables curved surfaces and small areas to be measured easily

DOI: A measure of how clearly a reflected image will appear in a reflective surface.

RSPEC: The peak gloss value over a very narrow angle.

Product Applications

Whilst glossmeters are widely used throughout industry to assess the reflective qualities of products, gloss information alone is limited as it tells us how much light is reflected, but nothing about the imaging forming qualities of a surface.

Phenomena such orange peel, haze effects and polishing marks distort reflections in a surface, seriously reducing visual appearance but cannot be measured with traditional glossmeter. This means two surfaces which have very different reflective properties often have exactly the same gloss value.

The DOI, Haze and RSPEC values measured by the Rhopoint IQ allow the user to quantify and control the surface textures that reduce the perceived quality of manufactured products.

Sample Applications:

		Paints and Coatings		Yacht Manufacturers
		Metal Polishers		Polished Stone
		Smart Phone, Tablet PC and Laptop Covers		Wood Coatings
		Automotive		Printing Ink
		Automotive re-finish		Powder Coating
		Automotive Coatings		Furniture
		Plastics Industry
