A screening device (110) for screening at least one plant specimen (112) in a plurality of plant specimens (114) is disclosed. The screening device (110) comprises a detector (116) adapted for acquiring spatially resolved images (117). The screening device (110) further comprises at least one selection device (118) adapted for selecting a single plant specimen (120) or a group of plant specimens (122) from the plurality of plant specimens (114) for imaging by the detector (116). The selection device (118) comprises a deflection device (124) adapted for deflecting electromagnetic waves propagating between the plant specimens (112) and the detector (116).
