Abstract

PURPOSE:To mass-produce detectors by providing a photoelectric converting element for illumination intensity detection with maximum sensitivity in the perpendicular direction on the internal bottom surface of a shield box that has an opening part for incident light at its front part and then by providing a mirror surface to at least one of the internal top surface and both side surfaces of the shield box. CONSTITUTION:On the bottom of shield box 1 of width W', photoelectric converting element 2 for illumination intensity measurement is provided at the center part of depth (d) from front- surface opening part 1a so that its maximum sensitivity can be obtained in its perpendicular direction. Further, reflex mirrors 7 and 8 of length l are provided on both its side surfaces coinciding with opening part 1a at their ends. Length l of the reflex mirrors should be equal to d-(DW'-W). However, W is the width of a window where the intensity of illumination is measured and D is the depth where the intensity of illumination is measured. Consequently, the optical arrangement of the illumination intensity detector can be made similar to that of a measurement chamber. If the room changes in size, changing l or putting out and covering mirrors 9 and 10, provided on the entire surfaces of both the side surfaces with shield films 13 and 14 is recommended. Consequently, its mass- production can be attained.
