Progress on the NIST IR-vis-UV Fourier transform spectrometer
Fourier Transform Spectroscopy(2022)
Abstract
Two years ago, NIST acquired a high-resolution Fourier transform spectrometer (FTS) from the Los Alamos National Laboratory [1, 2], The instrument has an unapodized spectral resolution of 0.0025 cm-1. We currently have optics and detectors to cover the wavelength range 200 nm to 2.5 μm, and will soon obtain a CaF2 beamsplitter to extend the range to around 8 μm and a KCL beamsplitter to cover the region 8-18 μm.
