Measuring CCT（Tcp）
OHSP350C could measuring the difference between CCT and Blackbody Δuv（commonly used to describe the value of color light source）.The color temperature of the light is defined as absolute temperature when a blackbody can emit a specific color light（unit：Kelvin）. A curve drawn from the color of light emitted by a blackbody at different temperatures is called”Black body Trajectory”.since the output of many light sources cannot fully fit with the blackbody curve ,it use ‘CCT’ to describe color.
