Light source for film scanner
 A light source for scanning a transparent film is equipped with a light intensity adjustment plate inserted between a light reflector and a light slot. The light intensity adjustment plate is partially painted to absorb light, so that the stronger light from the parallel center section of a linear light is weakened to produce a more uniform light along the whole scanning length. The light intensity adjustment plate can be placed between the U-shaped light tube, or attached to the inner wall of the U-shaped light tube housing. The light intensity adjustment plate can have a frame which is rectangular or concave. The light intensity adjustment plate can also have an shaped extension toward the light tube to produce more uniform light.
