An illuminant head assembly for a photographic film image scanner includes a linear light source, preferably a linear array of spectrally distinct illuminant elements combined with a main body having an elongate light conducting channel aligned with the light source and having a light pipe in the light conducting channel, the light pipe having a light diffusion material dispersed therein. The illuminant head assembly in a preferred embodiment includes additional light sources at one or both ends of the linear array and the main body includes additional light channels aligned with the additional light sources, the additional light sources and channels serving as illuminant sources for scanning marginal regions of the photographic film in the film scanner.

[ What is claimed is:] [1.]1. An illuminant head assembly for a photographic media image scanner comprising:a linear light source; anda main body having a first elongate planar light conducting channel aligned with said linear light source, said light conducting channel including a planar light pipe

[ What is claimed is:] [1.]1. An illuminant head assembly for a photographic media image scanner comprising:a linear light source; anda main body having a first elongate planar light conducting channel aligned with said linear light source, said light conducting channel including a planar light pipe therein, said channel and light pipe lying in a plane perpendicular to said photographic media and parallel to said linear light source, the light pipe having a light diffusion material dispersed throughout the light pipe as a sole light diffusing agent wherein said scanner comprises a film drive chassis with a film path having an elongate first scanning aperture coincident with image frames on the film and a second scan aperture coincident with an edge region of said film, the illuminant head assembly further comprising said planar light conducting channel having a length substantially coincident with the length of the first scanning aperture, and having a second light conducting channel adapted to be in alignment with said second scan aperture.
