Abstract

Apparatus for providing substantially two-dimensionally uniform irradiation of a relatively large planar target surface. Each of at least two substantially identical sources of radiation irradiate the target surface. The longitudinal axes of the sources of radiation are substantially parallel with each other, defining a plane substantially parallel to the target surface. Each of the sources of radiation is within a respective elongated elliptical reflecting trough and is spaced from the focal axis of the respective trough. Each trough terminates in an opening defining a rectangular plane substantially perpendicular to the major axis of the trough and substantially parallel to the longitudinal axis of the bulb.
