Raman spectra of different MoS2 layers acquired with an alpha300 microscope including RayShield Coupler (excitation wavelength: 532 nm; grating: 2400 lines/mm; integration time: 5s).
Raman image of a solution of L-cysteine in a mixture of water and different herbal oils. Most of the L-cysteine is dissolved in the water phase (blue). In the oil phase (yellow), an undissolved cysteine crystal (red) is visible. The green areas likely represent one of the herbal oil ingredients. The Raman spectrum of L-cysteine has characteristic peaks in the low-frequency range, which were clearly resolved by the alpha300 apyron equipped with the WITec RayShield coupler.
