Spectrometer and method for analyzing an object

The invention provides a spectrometer (1) for analyzing an object (7) provided with a transmitting device (2) which is adapted to a light beam (L) to emit; , (L) for receiving a receiver device (3) which is adapted to the to the object (7) the reflected light beam and outputting a measured value, wherein the measured parameter comprises a signal strength and / or signal-to-noise ratio; to vary and control means (4) which is adapted to an operating parameter of the transmission device (2) and / or the receiver means (3) to receive the corresponding one of the receiver means (3) output measured values, and on the basis of the dependence of the measured quantities of outputting the operating parameters of a reference signal for changing the measurement conditions to a user of the spectrometer (1)
