Claims

[Scope of utility model registration request]

A light guide consists of an output/input optical fiber, one end of which is connected to the light input/output section of the optical measuring instrument, and a light guide that is attached so as to cover the tip of the light guide. A holder forming a chamber into which a liquid enters, and a holder attached to a wall surface of the room opposite to the optical measuring device, the light guided from the other end of the input optical fiber to the other end of the output optical fiber. A light guide for reflection measurement, characterized in that it is equipped with a reflecting mirror that causes reflection, and a connecting pipe that is provided on the holder and communicates between a suction pump and/or a cleaning liquid tank disposed outside and the room. .
