Spectroscopy device and method for its implementation

Spectroscopy device (1) for analyzing a sample (E) by spectroscopy and including at least one spectroscopic probe (2) provided with:

• means (23) for illuminating the sample (E) to be analyzed with incident light;
• means (24) for collecting light re-emitted by the sample (E) to be analyzed under the action of the incident light;
• a contact surface (22), on the one hand, oriented towards the sample (E) to be analyzed, on the other hand, at the level of or near which (22) the illuminating means (23) and/or the collecting means (24) are located and, yet on the other hand, including at least one means (26;
• 26a;
• 26b) for receiving the light re-emitted by the sample (E);
• wherein:
• the probe (2) includes at least two different receiving means (26a;
• 26b), on the one hand, which the contact surface (22) includes, on the other hand, having each (26a;
• 26b) a different absorption, reflection and/or diffusion index and, yet on the one hand, each (26a;
• 26b) associated to at least part of the collecting means (24), and/or;
• the device (1) also includes an element (5) interposed between the contact surface (22) and the sample (E) to be analyzed, and designed to diffuse at least the incident light.
