    • The present invention relates to a light sensing device for exciting and detecting an emission of secondary light, especially of fluorescent light, from a test sample (40), comprising a light producing device (20) for producing sensing light in the form of a single bundle of light rays (21), as well as a deflection unit (10) to deflect the sensing light in at least one modifiable direction in order to sense at least one partial surface of the test sample (40), an imaging unit to image secondary light emitted from the test sample, and a detection unit to detect the secondary light. Unwanted long sensing times occur during fluorescent examination of a test sample having a large sensing surface and high local resolution. In order to reduce sensing times while maintaining high local resolution of said test samples, the inventive light sensing device has a splitting device (110) to divide the single bundle of light rays into at least two bundles of light rays (22,23), thereby resulting in a sub-division into fields instead of the usual sequential sensing of the test sample, said fields being simultaneously sensed by several beams of light. Sensing time can thus be reduced according to the number of simultaneously sensed test sample fields.
