• Benchtop Spectrophotometer of CS-820N for metal button Color Measurement


    Recently, we receive a custom inquiry for measuring metal button color. We separately measured the following two samples as target sample and sample to compare the LAB value.


    Today we will introduce how to measure it with Benchtop spectrophotometer CS-820N.
    It has 4 kinds of test calibers, we chose 6mm aperture size to measure the metal buttons.

    Test Condition
    1. Mode: Reflectance
    2. Light Source: D65
    3. Parameters need to Measure: CIE L*a*b, ΔE*ab

    Test Method

    1. One sample measure one same point to get the test result

      The following are the test results for all 2 samples

    Sample Name


    Target sample


    Color difference

    Test result
    L 65.15 65.03 dL*=-0.11 Pass
    a 1.28 1.10 da*=-0.18 Pass
    b 8.37 8.51 db*=0.14 Pass
    Total result dE*ab
    0.26 Pass
