Preferably, the camera bellows foreboard, camera bellows upper cover, camera bellows left plate, camera bellows right plate, camera bellows back plate, camera bellows bottom Plate must use black lucifuge material.

Preferably, the light source module can be dim light LED light or radioactive source.

The utility model has the advantages that：The utility model is simple in structure, the degree of automation is high, easy to operate, It can be widely applied to automatic while test the light intensity value of luminescent sample and the device of photodetector sensibility.
