Apparatus, a Handheld Electronic Device, and a Method for Carrying Out Raman Spectroscopy

摘要

An apparatus, a handheld electronic device and a method for carrying out Raman Spectroscopy are disclosed. In an embodiment an apparatus includes at least one optoelectronic laser configured to provide excitation radiation to a sample, the excitation radiation being generated by an electric current flowing through the at least one optoelectronic laser during operation of the apparatus and a transistor configured to modulate the electric current flowing through the at least one optoelectronic laser, to thereby switch on and off generation of the excitation radiation.
