Spectral tester

explain:The BGD 557 spectrophotometer adopts the principle of precision light splitting using a combination of LEDs. The light is separated by a certain wavelength interval, and then several sets of sensor arrays are used for photosensitive analysis. Compared with the traditional filter type colorimeter, the spectral colorimeter has higher accuracy and is very sensitive to any color. In addition to accurately measuring Lab value and dE value, it can also directly display the spectral reflectance curve, realize the color matching function, and accurately calculate the real parameters of various colorimeter formulas.

During the product development process, Biuged's R&D engineers measured various samples ranging from dark to light, white to black, as well as standard color samples provided by the International Organization for Standardization. The tested parameters were fully in line with international standards. At the same time, we also compared the test data of spectrophotometer from imported brands such as Japan, the United States, and Germany. Regardless of the color, we were able to control the maximum difference in Lab within ± 1.0. This is a breakthrough in Biuged's high-tech, achieving full compatibility with the international market.
