Abstract: A microdensitometer system capable of micrometer resolution for reading radiochromic films, includes: a film holder for supporting a radio chromic film sample; a high-precision scanning stage including a monochromatic light source for illuminating the film sample; a CCD microscope camera for a photographing light from the light source that is transmitted through the film sample; and a microcomputer for analysing data relayed from the CCD microscope camera. The film sample is translated by the scanning stage to enable analysis of the whole film sample.
