发明名称 Luminescent Reaction Measurement Device
摘要 Light resulting from chemiluminescence inside a reaction chamber 4 is transmitted through a light transmitting window 3, a large part of the light is made incident on a photoelectric surface 71 of a photomultiplier tube 2 to generate photoelectrons, and these photoelectrons are successively multiplied by surfaces 79 at one side of dynodes 78a, 78, and 78b. Meanwhile, a part of the light that is not made incident on photoelectric surface 71 is made incident on and reflected by a surface 77 at the other side of dynode 78a, returned to reaction chamber 4 via light transmitting window 3, reflected further by light reflecting surfaces 40 and 41 inside reaction chamber 4, emitted again from light transmitting window 3, and made incident on photoelectric surface 71 of photomultiplier tube 2 to generate and multiply photoelectrons in the same manner as the above. The amount of light made incident on photoelectric surface 71 is thus increased by the amount corresponding to the reflection at surface 77 at the other side of the dynode, thereby enabling detection of light caused by weak chemiluminescence.
