ABSTRACT:
An illumination device for a film image scanning device is provided. The illumination device is small in size compared to a size of the image to be scanned. Light emitted by a point light source at one end of the image scanning device is reflected back toward the point light source by first and second mirrors at an opposite end of the image scanning device. A third mirror reflects the light to a pair of condenser lenses that evenly transmit the light toward a film slide to be scanned. The light passes through one of the condenser lenses perpendicular to an optical axis of the condenser lens, thereby making the image scanning device compact. Fresnel lenses are also provided as condenser lenses.
