1. A system for optical detection of emitted radiation from microlocations on an object to be examined, comprising:

  • a light source providing excitation radiation characterized in that the diameter of the excitation radiation when illuminating the microlocation is of the same diameter or less than the diameter of the microlocation to be examined, a confocal scanning system adapted to receive the excitation radiation and direct it to the microlocation and to provide reflected radiation and emitted radiation from the microlocation, a first detector adapted to receive the reflected radiation and a position detection system, the first detector having an output connected to a position detection system, a second detector operatively positioned to receive the emitted radiation from the microlocation, the detector characterized in that the diameter examined by the detector is less than or equal to the diameter of the excitation radiation, and a control system coupled to the position detection system which causes the confocal scanning system to direct excitation radiation to a specific microlocation.
