The responsivity of two optical detectors was determined by the method of direct substitution in four different NIST measurement facilities. The measurements were intended to demonstrate the determination of absolute responsivity as provided by NIST calibration services at laser and optical-communication wavelengths; nominally 633 nm, 850 nm, 1060 nm, 1310 nm, and 1550 nm. The optical detectors have been designated as checks standards for the purpose of routine intramural comparison of our calibration services and to meet requirements of the NIST quality system, based on ISO 17025. The check standards are two optical-trap detectors, one based on silicon and the other on indium gallium arsenide photodiodes. The four measurement services are based on: (1) the laser optimized cryogenic radiometer (LOCR) and free field collimated laser light; (2) the C-series isoperibol calorimeter and free-field collimated laser light; (3) the electrically calibrated pyroelectric radiometer and fiber-coupled laser light; (4) the pyroelectric wedge trap detector, which measures light from a lamp source and monochromator. The results indicate that the responsivity of the check standards, as determined independently using the four services, agree to within the published expanded uncertainty ranging from approximately 0.02 % to 1.24 %.
在四个不同的美国国家标准与技术研究院（NIST）测量设施中，采用直接替代法测定了两个光学探测器的响应度。这些测量旨在证明NIST校准服务在激光和光通信波长（标称值为633 nm、850 nm、1060 nm、1310 nm和1550 nm）下对绝对响应度的测定。基于ISO 17025，这些光学探测器被指定为检查标准，用于我们校准服务的常规内部比较，并满足NIST质量体系的要求。检查标准是两个光阱探测器，一个基于硅，另一个基于砷化铟镓光电二极管。这四项测量服务基于：（1）激光优化低温辐射计（LOCR）和自由场准直激光；（2）C系列等温量热计和自由场准直激光；（3）电校准热释电辐射计和光纤耦合激光；（4）热释电楔形阱探测器，用于测量来自光源和单色仪的光。结果表明，使用这四项服务独立测定的检查标准的响应度，在公布的约0.02%至1.24%的扩展不确定度范围内相符。
