Abstract

Polaroid-Land Type 46-L Projection Film is investigated as a medium for recording optical spectra for the purpose of qualitative and quantitative spectrochemical analysis. The film's high spectral sensitivity extends from 3000 to 6000 A. In the analytically important 3000-4000 A region, emulsion contrast is found to be adequate and reasonably constant, gamma averages to about 2.3 and is reproducible to within ±0.1 from frame to frame. Speed is sufficient for nearly all spectrochemical purposes. Resolution of at least 30 lines/mm is obtainable. Analytical precision resulting in a coefficient of variation of less than ±5% indicates that Polaroid films are likely to find some utility in quantitative as well as qualitative analysis.
