CM-512m3
Spectrophotometer (spectral type, multi-angle)
Multi-angle spectrophotometer for metallic colors.
Features
Product Overview
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.
Principal Applications
Management of metallic colors
Main Features
Multi-angle design
A single operation allows measurements to be taken simultaneously from three different angles (25°, 45°, and 75°)
Ring illumination
With illumination provided from 18 radial directions, the effect of workpiece orientation on measurement results can be eliminated.
Line graph display
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
With the CM-512m3, the ΔE00 (CIE 2000) equation is used with parameters fine-tuned based on proprietary knowhow to provide measurement data for metallic/pearl coatings which correlate well with visual evaluation.
Surface color calculation
Color value: L*a*b* , L*C*h,
Color difference: ΔL*a*b*, ΔL*C*H*, ΔE*ab, CMC(l:c) , ΔE00(CIE DE2000)
Standard Observer: 2°/10°
Standard Illuminant: A, C, D50, D65, F2, F6, F7, F8, F10, F11, F12
Average measurement
The CM-512m3 supports automatic average measurement and manual average measurement. In the former, precision is increased by taking multiple measurements of the same specimen location setting; in the latter, measurements of different specimen locations are performed to efficiently determine the overall average data. In addition, an outlier elimination function allows the two measurements with the greatest difference from the average to be removed before calculation is performed.
Color-difference limit evaluation
Judgment as to whether or not a measured color is within a specific range can be made at a glance, thus simplifying quality-checking procedures.
440 data storage capacity
The CM-512m3 can store a total of 440 items of color-difference target data and measurement data.
