INTRODUCTION

The Optoelectronics Division, in some cases in collaboration with the Precision Engineering Division, provides a variety of Standard Reference Materials (SRMs) for the optoelectronics industry. An SRM is a material or artifact that has had one or more of its physical- or chemical-property values certified by technically valid procedures and is accompanied by a certificate issued by NIST. Examples of SRMs currently available are shown in the accompanying photograph. Please select one of the categories to your left for more information on these and other SRMs under development, as well as alternative measurement services and artifacts that are available in some cases.

The primary documentation associated with an SRM is its certificate. This provides customers with sufficient information to know whether the SRM will meet their calibration and/or traceability needs, to understand its proper use along with storage and aging considerations, and to understand the basis for the statement of certified values and associated uncertainties. The documentation also provides a thorough technical basis for the SRM or provides references to where that information is available.
