PURPOSE:To make possible the direct measurement of the quantity, illuminance, etc. of UV rays by providing an optical transmission body having a light incident end and light exit end and a UV ray measuring system. CONSTITUTION:The optical transmission body 11 is inserted into a transparent pipe and the quantity, illuminance, etc. of the UV rays in the pipe are measured. The UV rays in the pipe are conducted from the light incident end 12 through the body 11 to the light exit end 13 and are made incident on a sensor 17 from a photodetecting part 16 of a dark box 15. The sensor 17 detecting the UV rays inputs the measurement signal corresponding to the quantity of the detected light to a measuring calculator 18. The calculator 18 which receives said signal determines the quantity, illuminance, etc. of the detected UV rays in the pipe by an electrical or electronic arithmetic processing. The measuring accuracy is thus improved. |
