Extreme ultraviolet spectra from a tin laser produced plasma have been recorded over a range of angles between 20 deg. and 90 deg. from the target normal. Absolute intensity measurements are presented of both the 2% band centered on 13.5 nm and the total radiation emitted by the plasma between 10 and 18 nm. The in-band intensity is seen to be relatively constant out to an angle of 60 deg. from the target normal, beyond which it drops off quite steeply. The spectra at wavelengths greater than 13.5 nm are strongly influenced by self-absorption by ions ranging from 6{sup +} to 10{sup +}.
