BGD 557 Spectrophotometer uses the principle of combination LED precision spectroscopy, separating the light according to a certain wavelength interval and employing groups of sensor arrays to perform sensitive analysis. The BGD 557 Spectrophotometer, with higher accuracy, is very sensitive to any colors. It can measure not only L*ab value and delta E value accurately but also display a spectral reflectance curve, enabling the realization of color matching functions and the calculation of the real parameters of various color formulas.
During the R&D process, our scientists and engineers measured various color samples from dark to light, white to black, and other standard color boards provided by ISO (International Standardization Organization). The parameters of the test results are integrated with international standards.
We also analyzed parameters from Japanese, American, and German spectrophotometers. The differences in L*ab absolute values between them are within ±1.5. When comparing the L*ab values between BGD 557 and Japanese spectrophotometers, the largest L*ab difference is within ±1.0. This is a breakthrough in BIUGED's high technology, which achieves full compatibility with the international market.
