ABSTRACT:
A bioassaying device for carrying out an experiment with a subject placed under a transparent portion of a base plate. The subject is irradiated with light rays emitted from light-emitting ends of three fiber optic cables. One of the three fiber optic cables radiates light rays containing plenty of the red color-spectrum component, another cable radiates the blue component and the remaining cable radiates the green component. Each of the fiber optic cables is provided with a mechanism for adjusting its inclination angle simultaneously with vertical movement of a moving plate upon which the fiber optic cables are mounted.
