Abstract: A spectroscopy system (10) for analyzing in-elastic scattered electromagnetic radiation from an object being irradiated by electromagnetic radiation is provided. The system comprises a tunable lens assembly (13) having a tunable lens provided in the beam path between an electromagnetic radiation source (11) and the object (0) and arranged to project a beam of electromagnetic radiation emitted from the electromagnetic radiation source onto an area of the object and receive and collimate the in-elastic scattered electromagnetic radiation from the object. Based on electromagnetic radiation detected by at least a first detector (121) a control unit (14) is capable making a decision to change the operational settings of the tunable lens.

Abstract: The present invention relates to a method (500) for enhancing a Raman contribution in a spectrum of a sample (102), the method (500) comprising: Recording (504) a first spectrum of light (200) comprising information associated with ambient light and a first measurement response, wherein the first measurement response comprises a first optical response and a first Raman response of the sample (102) in response to being illuminated with light (104), having a first spot size (103b), from a light source (110). Recording (508) a second spectrum of light (300) comprising information associated with ambient light and a second measurement response, wherein the second measurement response comprises a second optical response and a second Raman response of the sample (102) in response to being illuminated with light (104), having a second spot size (103a), from the light source (110). Wherein the first spot size (103b) is larger than the second spot size (103a), whereby a contribution, to the first measurement response, of the first Raman response in relation to a contribution of the first optical response is smaller than a contribution, to the second measurement response, of the second Raman response in relation to the second optical response. Forming (510) a data set (400) based on a dissimilarity between the first spectrum (200) and the second spectrum (300), thereby enhancing a contribution of a Raman response to the formed data set (400). A spectroscopy system (100), a computer program and a non-transitory computer-readable storage medium are also disclosed.

Abstract: A device for detection of a substance by Raman spectroscopy comprises a holder (40) with an area (41) adapted for receiving a sample of the substance and a vibration engine (42). The vibration engine (42) is configured to move the holder (40) in a three-dimensional motion when the area (41) with the substance is arranged in front of a focusing lens (FL) of the spectrometer to provide a large actual sampling area and hence to achieve a strong signal at detection. The device comprises a SERS surface (30) arranged at the area (41) of the holder (40) for adsorption of the sample of the substance. A method for detection of a substance by use of the device is also presented.
