An attempt was made to correct the spectral sensitivity of a silicon photodiode, by using optical filters, to match the spectral sensitivity of Kodalith ortho film, type 3, 2556, and Kodalith pan film, 2568, respectively. The correction would allow the diode to be used with a light-integrator and light source of varying spectral power distribution, when these films are used. A Corning 978 2 blue/green filter was used for the ortho film and an O.C.L.I. detector trimmer, was used for the pan film. Through experimentation and statistical analysis, it was found that there was 100% correction of the photodiode spectral response, with the Corning filter, from 3200K to 2600K, for the ortho film. There was, however, only partial correction by the O.C.L.I, detector trimmer, of the pan film, from 3200K to 2900K.
