The Extreme Ultraviolet Imaging Spectrometer (EIS) is currently under development for flight on the Japanese Solar-B satellite. EIS uses a multilayer-coated off-axis telescope mirror and a multilayer-coated toroidal grating spectrometer to produce stigmatic spectra of solar regions isolated by a 1024 arcsec high slit. The instrument produces monochromatic images either by rastering the solar image across a narrow entrance slit or by using a very wide slit. Half of each optic is coated to optimize reflectance at 19.5 nm, and the other half to optimize reflectance at 27.0 nm, with each wavelength range imaged onto a separate CCD detector. EIS can provide key dynamical and density diagnostic information. Combining EIS data with observations from the other instruments on Solar-B should provide a detailed picture of solar atmospheric processes from the visible surface into the corona. In this presentation, we provide details of the instrument's expected performance based on calibration of the individual flight optics and end-to-end testing at the Rutherford Appleton Laboratory in the UK.
