Spectrocolorimeter Geometry

The d/8 (diffuse/8 degree observation) geometry is a common structure for spectrocolorimeter, which means that the light source is evenly illuminated on the sample surface through a diffuser (such as an integrating sphere), and the observation angle is fixed at 8 degrees. This geometry can simulate a variety of real-world lighting conditions, making the measurement more accurate and able to measure materials with different surface characteristics.

SCI/SCE mode:

SCI (Specular Component Included): Contains specular reflection components, which are used to evaluate the overall appearance and glossiness of the material.

SCE (Specular Component Excluded): Excludes specular components, focuses on surface color, and is not affected by gloss.

Through SCI/SCE technology, the Spectrocolorimeter can flexibly choose whether to include specular reflection light during measurement, which is suitable for more accurate analysis of surface gloss and color.

Spectrocolorimeter Features and Benefits:

High accuracy and repeatability : The biggest advantage of the Spectrocolorimeter is that it provides highly accurate color data through full spectrum analysis. It can measure a variety of optical properties including reflectance, transmittance, and surface gloss, and is particularly suitable for color measurement under strict lighting conditions.
Full spectrum measurement : The instrument is able to analyze the visible light spectrum from 400nm to 700nm, ensuring accurate measurement results even in complex lighting environments. Especially when dealing with fluorescent materials or high-gloss surfaces, the Spectrocolorimeter can easily cope with it, avoiding spectrum loss or inaccurate measurements.
Flexible geometry : Spectrocolorimeter usually adopts d/8 (diffuse/8 degree observation) or SCI/SCE mode, which can flexibly choose whether to include specular reflection light. This makes it more flexible and accurate when measuring glossy surfaces.
Advanced Color Management : The Spectrocolorimeter is equipped with SQCX software, which enables comprehensive color analysis and data management. It can record data in multiple color spaces, generate detailed test reports, and allow customization of color management processes to improve the efficiency of quality control.

FAQs About Spectrocolorimeter

Record the L*a*b values of the sample and the reference with a calibrated spectrophotometer or colorimeter. Compute the difference in the color by use of ΔE. The lower the Delta E, the more accurate the result. The difference in energy, ΔE < 1, is generally assumed to be invisible to the eye.

The concentration of colored compounds in a solution is determined by the use of a colorimeter test. It can be used to measure the quality of the product. The colorimeter test determines the presence of contamination or observes chemical reactions by measuring the extent to which a solution absorbs light at a given wavelength.

a. If this phenomenon occurred, it means the battery power is not enough. You need to charge the battery.

b. When charge the battery, please insert the battery to the instrument, and plug in the adapter to charge the battery. After 5 minutes, the instrument can be turned on.

c. If the instrument still cannot be turned on after charging 5 minutes, you can pull out the adapter and re-plug in to check it. Or repeat this operation.

d. If the instrument still cannot be turned on after charging 5 minutes, you can turn off the colorimeter and turn on it again to check it. Or repeat this operation.

e. If you have tried all the methods above but the colorimeter still cannot be turned on, please change the battery.

The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.

CIELAB L*a*b* values are the most standardized units in the use of color measurement. These determine values of lightness (L*), red-green (a*), and blue-yellow (b*). The color differences between the two samples can be measured through ΔE.

a. Right click "! USB Device" or "! SCI USB2Serial (COM6)", "Update Driver" -> "Install from a list or specific location (Advanced)" -> "Next" ->"Include this location in the search" -> "Browse", specify USB driver file path "CQCS3USB_Driver", click "Next". Then it will install successfully.

b.Detailed installation information please refers to "2.2 Installing USB Driver" in Color Quality Management System User Manual.doc.
