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.

sample

today we will introduce how to measure it with .
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

one sample measure one same point to get the test result

the following are the test results for all 2 samples

sample name	parameters	target sample	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

with large aperture 25.4mm is very suitable to measure metal materials. instrument repeatability and precision are both very good.
if any similar project inquiry, you are welcome to contact us for more details. we will help to recommend the most suitable instrument for customers.
