The Extreme ultraviolet Imaging Telescope (EIT) is an extreme ultraviolet imaging telescope, that will return EUV images of the sun in one of four wavelengths. Its normal incidence multilayer-coated optics will select spectral emission lines from Fe IX (171 å), Fe XII (195 å), Fe XV (284 å), and He II (304 å) to provide sensitive temperature diagnostics in the range from 0.06 MK to 3 MK. The EIT has provided wide-field images of the corona and transition region on the solar disc and up to 1.5 Rs above the solar limb. The telescope has a 45 x 45 arcmin field of view and 2.6 arcsec pixels which provide approximately 5-arcsec spatial resolution. The EIT probes the coronal plasma on a global scale, as well as the underlying cooler and turbulent atmosphere, providing the basis for comparative analyses with observations from both the ground and other SOHO instruments. This information is from the EIT instrument paper by Delaboudiniere et al. (1995).
