Colored glass is formed by adding colorants when firing ordinary glass. Among them, the addition of different raw materials, the length of firing time and the measurement of colorant will affect the color change of colored glass to varying degrees. The biggest factor is the addition of colorants, most of which are metal oxides. For example, when manganese dioxide is added, the glass is purple; Sulfur is added, and the glass is amber, etc.
Colored glass is used in many places, and the most widely used is in interior decoration. Among them, colored glass domes and windows in religious buildings are the most famous. On the car glass, dark tinted glass is generally installed, which can absorb heat and light; The development of colored glasses has met the needs of people. It can be seen that colored glass is widely used in life.
Experimental process
Six colored glasses of different colors were purchased in the market. Hl-10000-mini tungsten halogen lamp, xsm11639 optical fiber spectrometer, collimator and some optical fibers were used to complete the construction of transmittance measurement device to measure its transmittance.
Experimental result
Through the measurement of colored glass of six colors, we can get the spectral diagram of transmittance, view the transmittance of any wavelength point, and directly read the indicators such as total transmittance, chromaticity coordinates and color difference value, so as to evaluate the colored glass intuitively.
According to the software results in the figure above, we can easily read the coordinate values of CIE XYZ, CIE XYZ and CIE LAB chromaticity evaluation standards of the tested colored glass, and can match and compare the standard color cards of different evaluation systems.
In addition, the software also gives the comprehensive transmittance values of the full band and 380nm-780nm spectral bands of colored glass. At the same time, it can also give the transmittance of single wavelength points such as 380nm and 400nm, which can visually evaluate the transmittance of colored glass. We can also customize the display of the transmittance of the band or single point to be tested, that is, we can evaluate the transmittance of light of different colors.
To sum up, we can objectively judge the color deviation of the tested object according to the chromaticity coordinate value to control the color quality of industrial products. You can also test the transmittance of specific bands for glasses and glasses of different colors, such as green light, red light, ultraviolet light and other indicators.
