Characteristics and performance of a VUV spectrometer

Spectroscopic applications performed within the vacuum ultraviolet (VUV) range often employ special spectrometers equipped with VUV-sensitive optical components and detectors. In the present technical note, we briefly describe different parts as well as performance characteristics of a deep/vacuum UV spectrometer used to disperse radiation in the 40–160 nm range emitted from a laser-generated plasma source. Results demonstrate that the spectrometer produces quasi-stigmatic images with corresponding resolving power and instrumental band-width of 40,800 and 0.042 nm, respectively.
