Abstract

The invention discloses a device 20 for performing near field Raman spectroscopy comprising a light beam confinement unit 21 for forming a focal field of a transmitted incident light 23, and a sample stage 30 for providing a test sample 32, which is analysable with the incident light 22 passing through said light beam confinement unit 21, wherein said sample stage 30 is designed to move in at least two spatial directions. A spherical near field source device 25 is arranged between said light beam confinement unit 21 and said sample stage 30, wherein said spherical near field source device 25 is arranged in a focal field of said light beam confinement unit 21 for providing a near field into the test sample 32. Furthermore, the invention discloses a method for investigating a test sample with near field Raman light, a computer program, a computer-readable medium and an apparatus for performing Raman spectroscopy.
