Abstract

Standard Reference Material (SRM) 2517a is an optical-fiber-coupled wavelength reference based on the fundamental absorption lines of acetylene in the 1510 nm to 1540 nm region. The main difference between SRM 2517a and its predecessor, SRM 2517, is the use of lower pressure in the acetylene cell to produce narrower lines. Thus SRM 2517a extends the use to higher resolution and higher accuracy applications. The center wavelengths of 56 lines of the v₁ + v₃ rotational-vibrational band of acetylene ¹²C₂H₂ are certified for this SRM. Fifteen lines are certified with an uncertainty of 0.1 pm, two lines are certified with an uncertainty of 0.6 pm, and the remainder of the lines are certified with an uncertainty of 0.3 pm. This document describes SRM 2517a and details the uncertainty analysis.
