[. . . ] Multi-Angle Spectrophotometer
CM-512m3
Ideal for On-site Operation & Curved Surface Measurement!
Multi-angle type spectrophotometer
The color of metallic/pearl coatings can be inspected easily.
The CM-512m3 measures colors by illuminating subjects from three angles simultaneously (25º, 45º and 75º), 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. [. . . ] Like visual evaluation, the multi-angle method obtains measured data by applying illumination from three different angles. Consequently, it is suitable for the evaluation of metallic/pearl colors.
Applications for coating measurements
Automotive exterior Even curved surfaces of car bodies or bumpers can be measured stably.
The portable, handheld design ensures easy and stable measurement on production sites.
The instrument can be held easily and firmly, and measurements can be taken without being concerned about its orientation (rotational deviation). Personal computers and home appliances Construction materials such as exterior walls and kitchen panels Office furniture
Applications for texture measurements
Textured materials used for automotive interiors
With the recently popular textured materials that have large and deep geometrical patterns, it is difficult to obtain color differences with integrating sphere (d/0) or 45/0 instruments. The CM-512m3 allows evaluation that correlates well with visual evaluation by obtaining data at the angles of 25º and 75º.
Measurement Principle
Illuminating/viewing optical system Illumination is applied in the form of rings at angles of 25º, 45º and 75º away from the perpendicular to the sample surface. The light reflected in the direction perpendicular to the sample surface is received. 25º: Corresponds to the highlight direction of visual evaluation 75º: Corresponds to the shade direction of visual evaluation Pre-flash function Pre-flash (at 2% of the intensity of full emission) is performed at the beginning of measurement to determine the optimal intensity for measurement according to the reflectance of the sample. This function reduces power consumption and improves repeatability when measuring samples with low reflectance.
