Abstract (en)
[origin: WO2009133302A1] The present invention relates to a device for analyzing a dissolved particle sample (2), said device comprising a microscope system (1), said microscope system (1) comprising a supporting means (3) for supporting said sample (2), an illumination means (4) capable of emitting a luminous energizing beam (10), a focusing means (5) for focusing said luminous energizing beam (10) into a focal point (12) on the sample (2), and a spatial filter means (7) capable of defining an analyzed space (13) around the focal point (12), and is characterized in that said microscope system (1) also comprises an enhancement means (14) for enhancing said luminous energizing beam (10), said enhancement means (14) having a strictly positive focal length and a refractive index greater than the refractive index of said sample (2), one portion of said enhancement means (14) being disposed on the path of said luminous energizing beam (10) downstream from said supporting means (3) and upstream from said focal point (12), and in that at least one portion (14") of said enhancement means (14) is not rigidly connected to the supporting means (3). The present invention also relates to a method for analyzing a dissolved particle sample (2) by such an analyzing device.
