Abstract: An optical calibration method for a spectrum measurement device including a light-input part includes: measuring a plurality of narrow-band rays by the light-input part to obtain a plurality of narrow-band spectrum impulse responses, respectively; establishing a stray light database according to the narrow-band spectrum impulse responses; generating a correction program according to the stray light database; measuring a spectral radiant standard light by the light-input part to obtain measurement spectrum data; and generating a calibration coefficient program based on the measurement spectrum data and spectral radiant standard spectrum data, wherein the calibration coefficient program matches the measurement spectrum data with the spectral radiant standard spectrum data, and the spectral radiant standard spectrum data is obtained by measuring the spectral radiant standard light by a standard spectrum measurement device. A spectrum measurement device, an optical measurement method and an optical calibration method are also provided.
