For very smooth and highly polished surfaces that
reflect images distinctly.
The incident light is directly reflected on the surface, i.e. only in the main direction of reflection.
The angle of incidence is equal to the angle of reflection.
On semi smooth surfaces the light is diffusely
scattered somewhat in all directions. The image
forming qualities are diminished: A reflected object no longer appears super brilliant, but semi blurred.
The more uniform the light is scattered, the less intense will be the
reflection in the main direction and the duller the surface will appear.
On rougher surfaces the light is diffusely scattered in
all directions. The image forming
qualities are much diminished: A reflected object no longer appears brilliant, but almost non-existent.
When one requires measuring all three types of surfaces
described above, we have a Novo-Gloss Trigloss unit that
simultaneously measures all three geometries. Immediately recognize deviations from the specification. With
all three geometries; 20°, 60°, 85°, in one unit, it is as handy as the one angle unit.
Having three geometries in one unit allows you
to be in compliance with international standards and to
quickly recognize quality variations. View one angle only or all three. All the selected geometries are
measuring at the exact same location. The results are displayed instantly, including statistics.
The Rhopoint IQ instrument measures the following parameters with a single button push:
20/60/85° GLOSS , HAZE, REFLECTED IMAGE QUALITY (RIQ) , DISTINCTNESS OF IMAGE (DOI) and RSPEC
A high quality finish is important in a number of industries.
Orange peel and haze have a huge impact on finish quality.
glossmeters cannot measure these effects that reduce visual quality.
