ルミノメーター（発光測定装置）

A luminometer is an instrument capable of detecting photons of light that are emitted from either a chemical or enzymatic reaction. This type of instrument can be a very useful piece of equipment for a variety of laboratories, including life science research, clinical, and applied areas such as food or water quality testing. Luminescence is typically a more sensitive detection modality than either fluorescence or absorbance-based methods, making it especially useful for studying cellular health and metabolism, genetic reporter assays, and even biochemical assays.

As light is emitted from a chemical or enzymatic reaction, the individual photons are collected by a detector, commonly either a photodiode or photomultiplier tube. This light is quantified as a Relative Light Unit (RLU) and is directly proportional to the concentration of the amount of luminescent material in the sample.  

When choosing a luminometer, important factors to consider include sensitivity, dynamic range and cross-talk performance, as the performance of the instrument can greatly impact the success of your assay results.
