阵列光谱辐射计广泛应用于光测量。然而，用户并没有广泛了解它们的特性。CIE 233:2019旨在向用户介绍阵列光谱辐射计的特性，这些特性对于获得准确的测量结果非常重要。此外，还提出了性能指标，使用户能够根据影响其应用的属性对仪器进行排序。在许多情况下，如果阵列光谱辐射计具有适当的特征，可以对测量值进行校正，从而提高精度。给出了这些更正的性质和用途的详细信息。讨论了各种常见量的校准程序和不确定度，为测量提供了良好的基础。 讨论的背景资料见附件和参考资料。

Array spectroradiometers are used pervasively in light measurement. However, their properties are not widely understood by users. CIE 233:2019 seeks to educate users in the characteristics of array spectroradiometers that are important to obtaining accurate measurement results. Moreover, performance indices are proposed that will enable users to rank instruments according to the properties that affect their applications. In many cases, if the array spectroradiometer is properly characterized, correction can be made to measurements that will improve the accuracy. Details of the nature and use of these corrections are given. Calibration procedures and uncertainties are discussed for various common quantities, giving a sound foundation to measurements. Background information, underlying the discussions, is found in the annexes and references.
