The results of an investigation of the metrological characteristics of a standard, which can store, reproduce and transfer the unit of average power from 0.1 to 5 mW in the 0.6-1.7 µm spectral range with a relative expanded uncertainty not exceeding 0.002, and an attenuation from 0.05 to 60.00 dB, with an expanded uncertainty of less than 0.2 dB, are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
