Description of the Related Art In a weather resistance tester, in order to obtain stable test results, it is necessary to carry out a test with a constant ultraviolet illuminance. As shown in FIG. 4, a weather resistance tester generally used in the past is constructed by providing a light shield on the surface of a transparent quartz rod 1 with a light receiving window 2 left. As the light shield, for example, an aluminum film and a silicon dioxide film are alternately deposited. Further, the tip of the translucent quartz rod is cut diagonally so that ultraviolet rays are reflected from the same and effectively enter the light receiving element.
