The project consists of a 1.7m telescope with instrumentation able to perform: a) high resolution (R ≥50 000) spectroscopy by means of two echellé spectrographs covering the 115–310 nm spectral range; b) long slit (1x75 arcsec) low resolution (R ∼ 1000) spectroscopy with a near-UV channel and a far-UV channel to cover the 115–305 nm spectral range; c) near-UV and a far-UV imaging channels covering the 115-320 nm wavelength range; d) slitless spectroscopy with spectral resolution of about 500 in the full 115–320 nm spectral range. Here we present the WSO-UV focal plane instruments, their status of implementation, and the expected performances.engjournal articlehttps//doi.org/10.1117/12.2055513http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=1891986restricted access52Ultraviolet: generalSpace vehicles: instrumentsAstronomía (Matemáticas)21 Astronomía y Astrofísica
