Sanyuanse TC-1008d Spectrophotometer:

Product Introduction and Industry Applications (Including Specifications and Color Difference Calculation)

The Sanyuanse TC-1008d Spectrophotometer is a high-precision, portable industrial color measurement device. Featuring a d/8° integrating sphere geometry, it supports dual-mode SCI/SCE measurements and covers a wavelength range of 360–780 nm, enabling the precise analysis of fluorescent samples.
Primarily utilized for the acquisition of color parameters and the calculation of color differences, this device is tailored for use across 12 major industries, offering a blend of professional-grade performance and practical utility.
This device accurately outputs color space parameters across multiple systems, including Lab, XYZ, and RGB. An illustrative example comparing parameters for a standard sample against a measured sample is as follows: The standard sample yields Lab values ​​of L=80.2, a=1.5, and b=10.3; XYZ values ​​of X=72.1, Y=75.3, and Z=80.5; and RGB values ​​of R=225, G=220, and B=208.
The measured sample yields Lab values ​​of L=81.5, a=1.2, and b=11.1; XYZ values ​​of X=73.4, Y=76.8, and Z=82.2; and RGB values ​​of R=228, G=222, and B=205.

The core formula for color difference calculation uses the industry-standard CIE 1976 equation: color difference (Delta E 1976) equals the square root of (lightness difference squared plus red-green difference squared plus yellow-blue difference squared). In this case, lightness difference (Delta L) = 81.5 – 80.2 = 1.3; red-green difference (Delta a) = 1.2 – 1.5 = -0.3; and yellow-blue difference (Delta b) = 11.1 – 10.3 = 0.8. Substituting these values into the formula gives a calculated color difference (Delta E 1976) of approximately 1.52,
