The average luminous intensity is obtained by summing the luminous intensity of each segment and dividing by the total number of segments. 2. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE (International Commission on Illumination) eye-response curve. 3. Clean only by pure water, isopropanol, ethanol, Freon TF (or equivalent).
