Patent ID: 10317655

Abstract:
The invention relates to a microscope for the molecular spectroscopic analysis of a sample (2), having a beam path having at least one quantum cascade laser (QCL) (3) which emits an infrared (IR) radiation, a phase modulator (5) which is arranged between the QCL (3) and the sample (2), at least one optical element (6) which is arranged between the phase modulator (5) and the sample (2) and a sensor (4) which detects an IR radiation which is transmitted and/or reflected by the sample (2). The invention relates further to a method for the molecular spectroscopic analysis of a sample (2) comprising the steps of irradiating the sample (2) with an infrared (IR) radiation by means of a quantum cascade laser (QCL) (3), wherein the IR radiation is directed onto the sample (2) via a phase modulator (5) and at least one optical element (6), and detecting the IR radiation which is reflected and/or transmitted by the sample (2).
