Multi-angle Spectrophotometer CM-512m3

Model:CM-512m3
Brand:

The CM-512m3 measures color by illuminating subjects from three angles simultaneously (25°, 45° and 75°), making it suitable for subjects such as metallic/pearl coatings used for automotive exteriors or for the textured materials used for automotive interiors and allowing the changes in color according to the illumination angle to be measured.
Unlike conventional spectrophotometers, correlation of the measurement results with visual evaluation of such subjects can be achieved.
This special geometry is truly symmetric and therefore free of orientation errors often found in traditional multi-angle instruments.
In addition, this illumination gives very accurate results even when curved surfaces are measured. Therefore difficult samples such as vehicle mirror bodies or door handles can be measured easily.
The graph display function enables easy color judgment even on production sites without using a personal computer.
Evaluation equation suitable for measurements of metallic/pearl coating correlates well with visual evaluation
