Detection end and detection equipment

The utility model discloses a detection end, which comprises a first light source device, a spectrum acquisition device and a cable, the first light source device and the spectrum acquisition device are integrated in the detection end, and the cable is connected with the detection end. The first light source device emits exciting light, so that the exciting light is emitted into a to-be-detected water body, the spectrum acquisition device is used for acquiring light which comes from the to-be-detected water body and is generated under the irradiation of the exciting light, acquiring spectrum data based on the acquired light, and acquiring a detection result of the to-be-detected water body according to the acquired spectrum data. The detection end is placed in the water body to be detected, the placement depth can be changed, and different depths of the water body to be detected can be detected through the detection end, so that the detection end can realize on-line in-situ detection of algae in the water bod
