DEVICE FOR CAPTURING FULL-SURFACE IMAGES OF A CELL CULTURE PLATE WITH ONE OR MORE CAVITIES

The invention relates to an apparatus (1) for establishing the effect of active ingredients on nematodes and other organisms in aqueous tests, comprising a holder (40) for receiving a cell culture plate (50) with wells (57), in which the nematodes with the active ingredients can be filled, wherein the cell culture plate (50) has a bottom side (51), a top side (52) and a plurality of side faces, which extend between the bottom side (51) and top side (52), a camera (20) that serves to record images of preferably the bottom side (51) of the cell culture plate (50), and an illumination device (30) for illuminating the cell culture plate (50), wherein the illumination device (30) comprises a plurality of light sources. According to the invention, in the use position of the cell culture plate (50), provision is made for the light of a first light source (31) to enter the cell culture plate (50) from the outside through a first side face (53), the light of a second light source (32) to enter the cell culture plate (50) from the outside through a second side face (54), the light of a third light source (33) to enter the cell culture plate (50) from the outside through a third side face (55) and the light of a fourth light source (34) to enter the cell culture plate (50) from the outside through a fourth side face (56). Moreover, the invention relates to a method for adjusting the individual light sources.
