Colorimeter is an instrument for measuring the color difference of an object. Can also be called colorimeter, color color difference meter, color difference analyzer, color difference tester, color difference meter, color difference detector, color difference meter, color difference calibrator, color difference meter, pigment color difference meter
Colorimeter classificationColorimeter can be divided into two categories according to different working principles: photoelectric integral colorimeter and spectroscopic colorimeter. Photoelectric integration type colorimeter commonly known as precision colorimeter, spectrophotometer commonly known as spectrophotometer.
According to the size of colorimeter can be divided into portable colorimeter and desktop colorimeter. The photoelectric integral type color difference meter has a simple structure and a low accuracy, and is only portable. The spectroscopic type requires the grating to separate the spectrum, so it can be divided into a portable spectrophotometer and a benchtop spectrometer.
According to the orientation of the test port, it can be divided into a test port, a test port, and a test port. Meet the needs of test objects in different states. Color Spectrum's precision colorimeter and portable spectrophotometer are tested with the test port facing downward. The bench-top spectrophotometer CS-800 with the test port facing upward is suitable for measuring particles, powders, pastes and other samples. At present, the color spectrometer technology research and development of the desktop spectrophotometric color measurement instrument CS-820 for the test port on the side, with a fixture, can be more convenient to fix and replace the sample.
Colorimeter working principlePhotoelectric integral type color difference meter
Using the instrument's internal standard light source to illuminate the measured object, perform an integral measurement over the entire visible wavelength range, directly measure the tristimulus value and chromaticity coordinates of the transmitted or reflected object color, and give the measured sample through a dedicated microcomputer system. The color difference between. Such as color spectrum science and Technology Co., Ltd. CS-10, CS-200, CS-210, CS-220 and other models of precision colorimeter using this working principle.
Automatically compare the color difference between the template and the tested product, and output the three sets of data of CIE_Lab and the color difference data of ΔE, ΔL, Δa, and Δb after color comparison, and provide the basis for the quality inspection of the product.
Spectrophotometer
The spectrophotometer measures the relative spectral power distribution of the light reflected by the object to obtain the reflection spectrum of the surface of the object. The weighted multiplicative value of the CIE spectrum is then multiplied by the three-stimulus value of the CIE spectrum. After the integration, the tristimulus value, color coordinate, color difference, etc. of the surface of the sample are obtained. Other parameters. The spectrophotometric colorimeter designed by the system is mainly divided into the main parts of the lighting and observation system, the spectroscopic system, the photoelectric detection system and the circuit control system. Color Spectrum Technology Co., Ltd. CS-580, CS-600, CS-610, CS-660 and other models of color difference meter for the split-type color difference meter, also known as spectrophotometer
