Abstract
An intensifying screen for imagewise exposing a radiographic element is disclosed comprised of a fluorescent layer capable of absorbing X-radiation and emitting longer wavelength electromagnetic radiation to which the radiographic element is responsive and a support capable of redirecting incident longer wavelength radiation back toward the radiographic element. The support includes in at least one portion reflective lenslets.
