What is a Spectrocolorimeter / Color luminance meter / Colorimeter?

The color luminance meter can measure the average brightness and chromaticity per area of ​​the light emitting surface (for example, the display of a personal computer) or the reflecting surface (the surface of a substance that is not emitted by itself). Luminance represents the brightness per unit of a shining surface, and chromaticity represents the numerical value of color using a function called the munsell color system. The numerical value of chromaticity is expressed by the color coordinates (x, y) and the brightness Y (cd / m2). Due to its non-contact and small size, it is used as a lot of quality control and sensors. In JIS, it is used for evaluation of retroreflection (reflection that returns to the direction of light irradiation) and performance evaluation of safety signs.

Application of Spectrocolorimeter / Color luminance meter / Colorimeter

The color luminance meter can measure the display of personal computers, mobile phones, camera displays, light sources of lamps and fluorescent tubes, large outdoor vision displays, painted surfaces of buildings, lamps and traffic lights of automobiles. You can perform quality control of industrial products, chromaticity, color difference, and color unevenness measurement. Since some displays of personal computers and televisions repeatedly emit light in an invisible short cycle, the chromaticity of broadcast images is measured with a color luminance meter that can measure brightness and chromaticity. This cannot be measured with a spectrophotometer. In addition, because the device is small and easy to carry, the landscape can be used for landscape assessment and landscape management because it can measure the effects of chromaticity, weather, and brightness due to the weather.
