Abstract

PURPOSE:To decide whether a multi-layer dielectric film is good or not easily and cheaply by arranging the photosensitive face of a light receiving element oppositely to the multi-layer dielectric film face and providing a hole, where the light from a light source and the reflection light from the multi-layer dielectric film face pass, in the light receiving element. CONSTITUTION:A solar battery is used as light receiving element 7, and light receiving element 7 is so arranged that the photosensitive face may be opposite to multi-layer dielectric film 10, and hole 8 where the laser light from the He-Ne laser tube of a light source and the reflection light from multi-layer dielectric film 10 pass is provided in light receiving element 7, and this measuring system is stored in dark box 14. A scattered light quantity, namely, the output voltage of the light receiving element measured by this unit is proportional to the laser output obtained by arranging the multi-layer dielectric film in the laser tube. Thus, it can be decided whether the multi-layer dielectric film is good or not cheaply with a high work efficiency.
