Colorimeter

The colorimeter comprises a scanning galvanometer and a spectrograph located on the light emitting side of the scanning galvanometer, the scanning galvanometer is used for scanning a to-be-detected screen, and light emitted by one light emitting point on the to-be-detected screen is obtained every time; the light emitted by each luminous point on the screen to be detected is reflected to the light incident side of the spectrograph; the spectrograph is used for detecting the light to obtain spectral information corresponding to each light-emitting point and converting the spectral information into chromaticity information of each light-emitting point. Therefore, the colorimeter adopts the spectrograph, the spectral information of each measurement point can be measured and then converted into the chromaticity information, and the measurement precision is high; and meanwhile, the colorimeter adopts a galvanometer scanning mode, so that the measurement speed is increased. 本申请实施例公开了一种色度仪，该色度仪包括：扫描振镜，以及位于该扫描振镜出光侧的光
