    Abstract: The present invention relates to a monochromatic measurement system. The system mainly includes a monochromator, a light-detecting device and a filter device. The monochromator functions to split light under test into respective light beams with different wavelengths. The filter device modulates the transmission efficiency of the respective light beams, so that the wavelengths of the light beams to which the light-detecting device displays a better response have a lower transmission efficiency while the wavelengths of the light beams to which the light-detecting device displays a lower response have a higher transmission efficiency. The response values measured by the light-detecting device with respect to different wavelength intervals are normalized accordingly. The measurement errors attributed to the measurement precision of the instrument and the environmental noise are independent from the variation of wavelength. The reliability of the measurement instrument is elevated.
