Many scientific topics, from nearby intrinsically faint stars to bright sources at the edge of the universe, benefit from wide instantaneous wavelength coverage at high efficiency. X-shooter is a high throughput single-target spectrograph installed on the ESO VLT, which obtains an intermediate resolution visible to a near-IR (0.3 to 2.5 micrometer) spectrum in a single exposure. The design uses dichroic splitters to feed cross-dispersed echelle spectrographs optimized for three wavelengths ranges. The instrument was installed on the VLT in 2009, and has already produced several refereed papers.
