title: Highly achromatic Fourier-transform spectrometer.
abstract: We present a simplified all-reflective Fourier transform spectrometer with a split-mirror configuration for use over a broad spectral range with spatially coherent sources. The device is particularly well suited for measurement of broadband laser-like light, with resolution limited by beam size and collimation. Spectra are taken in the near-UV and the mid-IR, a total span of 4.6 octaves, including an octave spanning spectrum. Potential sources of error are investigated both theoretically and experimentally.
