One-meter focal length grazing incidence spectrometer built in the Rowland circle configuration. This compact and versatile instrument allows the user to obtain a high quality time resolved VUV spectrum.

- Time resolution down to 5ns

- Broad spectral range

- High sensitivity


Rowland's spectrometer

A special MCP detector is placed in the cylindrical Rowland surface, which allows obtating high quality light spectrum with time resolution between down to 5ns. A special “no shadow” construction of the MCP housing ensurses high sensetivity of the detector and high level/noise ratio fot the VUV radiationg. A set of three gratings with different dispertion characteristics is used to provide an extended range (up to 36nm) of spectral coverage.
