Abstract
LEXI is a wide-field X-ray imager using bare-glass slumped micropore optics. The LEXI optic was recently characterized at PANTER to measure both the point spread function and the effective area as a function of energy. The effective area measurements were made with a continuum source in order to characterize the effective area curve at moderate energy resolution over the 0.2-4.0 keV range. Comparison of measurements with ray-tracing suggests a number of ways modeling can be improved in the future.
