Abstract:
An apparatus for providing substantially two-dimensionally uniform irradiation of elongated three-dimensional objects with a high level of irradiance, said apparatus comprising:a source of radiation for producing radiation to irradiate the surface of an elongated three-dimensional object; an elongated elliptical reflecting trough for reflecting light from said source of radiation and concentrating the reflected light on the surface of the object, the transverse cross-section of said trough being a portion of an ellipse having a major axis and a minor axis, said trough having a focal axis within the trough, said source of radiation being within said trough, on the major axis and spaced from the focal axis of said trough, said trough terminating in an opening defining a rectangular plane substantially perpendicular to the major axis of the ellipse of said trough and substantially parallel to the longitudinal axis of said source of radiation, said trough opening having upper and lower edges and right and left side edges; a substantially flat upper elliptical reflector connected to the upper edge of said trough and having a forward edge; a substantially flat lower elliptical reflector connected to the lower edge of said trough and having a forward edge; a substantially flat upper middle reflector extending from the forward edge of said upper elliptical reflector; a substantially flat lower middle reflector extending from the forward edge of said lower elliptical reflector; a substantially flat right side middle reflector extending from the right side edge of said trough; a substantially flat left side middle reflector extending from the left side edge of said trough; a substantially flat upper outer reflector extending from said upper middle reflector; a substantially flat lower outer reflector extending from said lower middle reflector; a substantially flat right side outer reflector extending from said right side middle reflector; and a substantially flat left side outer reflector extending from said left side middle reflector.
