Claims

[Scope of Claim for Utility Model Registration] (1) In an optical measurement device that irradiates light from one side of the object to be measured and performs light detection by bringing a light receiving device into contact with the object on the other side of the object to be measured. ,
An optical measurement device in which the light receiving device is provided with a hood that surrounds the photocathode, and the hood is used as a pressure switch. (2) In an optical measurement device that irradiates light from one side of the object to be measured and performs light detection by bringing a light receiving device into contact with the object on the other side of the object,
An optical measurement device in which a bundle fiber in which optical fibers are bundled is provided on the photocathode of the photodetector so that the optical fibers are perpendicular to the photocathode.
