Abstract Measurement of the spectral sensitivity of diazo paper, with monochromatic light that is given by combination of bright line spectrum of mercury lamp, cut-off filter and band-pass filter, is described in this paper. On two diazo papers used, maximum sensitivity wave length is approximately 4000Å, and the range of sensitivity is about 3000-4500Å. It has conformed to the spectral absorption characteristics of diazo materials. For 3650A radiation, given density 0.19 (at 5500Å), the absolute sensitivity of diazo papers has been 0.05-0.07 jule/cm2 and 0.09-0.11 jule/cm2 at 20C°.
