| Abstract: | With the improvement of living standard and the development of scienceand technology, the requirements for the quality of the lens of colour camerais becoming higher. The spectral transmittance and CCI (colour contributionindex) are two important quality indexes of the lens. The paper will describe the controlling circuit automatically measuring the spectral transmittance andCCI of the lens with double light paths, and flow chart calculating and printingthe spectral transmittance and CCI by means of microcomputer. |
