Hydrogen cyanide H13C14N absorption reference for 1530 nm to 1565 nm wavelength calibration - SRM 2519a



Sarah L. Gilbert, William C. Swann, C. M. Wang


Standard Reference Material (SRM) 2519a is an optical-fiber-coupled wavelength reference based on the fundamental absorption lines of hydrogen cyanide H13C14N in the 1530 nm to 1565 nm region. The main difference between SRM 2519a and its predecessor, SRM 2519, is the use of lower pressure in the hydrogen cyanide cell to produce narrower lines. Thus SRM 2519a extends the use to higher resolution and higher accuracy applications. The center wavelengths of 54 lines of the 2Ņ3 rotational-vibrational band of hydrogen cyanide H13C14N are certified with uncertainties ranging from 0.04 pm to 0.24 pm. This uncertainty is an improvement of more than an order of magnitude over SRM 2519. This document describes SRM 2519a and details the uncertainty analysis.
