Spectral Illuminance Meter

A spectrophotometer uses filters to isolate specific wavelengths of light and employs photoelectric sensors to measure the light intensity of each band. It is used to detect the spectral distribution, color temperature, and color rendering properties of light sources. In the printing industry, it monitors the color rendering effects of inks, and in the plastics industry, it evaluates the lightfastness of materials.
Selection
When selecting, focus on the wavelength range covering the application needs, precision matching the detection standards, and the probe type suiting the measurement scenario. Consider the instrument calibration cycle and ease of operation, and include the impact of environmental temperature in the evaluation.
