本文档描述了用于测量紫外、可见和近红外光谱范围内光谱反射率的仪器、标准和技术。本文件分为三个部分。第一部分介绍了维护用于光谱反射率测量的参考和传递光谱仪的指导思想，以及可用的标准和服务。第二部分介绍了NBS高精度参考分光光度计，包括专门开发的辅助折射率计。该仪器为制定漫反射和镜面反射的绝对NBS标准提供了基础。第三部分介绍了NBS转移分光光度计，一种高精度的商业分光光度计，用于校准标准参考物质（SRM），如漫反射和镜面反射标准。转移仪器依赖于主标准品，这些标准品在第二部分所述的高精度参考分光光度计上定期校准。转移仪器还用于对工业和政府的其他实验室提交的样品进行特殊测量。包含细节和方程式的参考文献转载于附录中。
This documentation describes the instrumentation, standards, and techniques used in the measurement of spectral reflectance over the ultraviolet, visible, and near infrared spectral ranges. The documentation is divided into three parts. Part I describes the guiding philosophy for maintaining reference and transfer spectrophotometers for spectral reflectance measurements, and standards and services that are available. Part II describes the NBS high accuracy reference spectrophotometer including specially developed accessory ref lectometers. This instrument provides the basis for the development of absolute NBS standards of diffuse and specular reflectance. Part III describes the NBS transfer spectrophotometer, a high precision commercial spectrophotometer used for calibrating Standard Reference Materials (SRMs) such as diffuse reflectance and specular reflectance standards. The transfer instrument relies on master standards that are periodically calibrated on the high accuracy reference spectrophotometer described in Part II. The transfer instrument is also used for performing special measurements on samples submitted by other laboratories in industry and government. References containing details and equations are reproduced in the appendices.
