Apparatus for measuring light |
摘要 |
A light sensor 10 includes two parallel, spaced mask plates 12, 14. A first mask plate 12 has nine, small, spaced holes 38a-i which are in alignment with corresponding holes 36a-i in the second mask plate 14. The light sensor 10 includes a base plate 18 having nine holes 22a-i into which photosensitive devices 26a-i are positioned and the base plate 18 is secured to the outer surface of the second mask plate 14. The photodiodes 26a-i are connected to an indicating means 32 which provides an indication of the light falling upon each photodiode 26a-i individually or upon all of the photodiodes 26a-i collectively.
