See Through Raman Technology: Expanded capabilities for through package identification using 785 nm and 1064 nm excitation Raman

See through Raman Spectroscopy (STRaman®) is a newly developed technology that expands the capability of Raman spectroscopy to measure samples beneath diffusely scattering packaging material. The STRaman technology features a much larger sampling area than the confocal approach. This design enhances the relative intensity of the signal from the deeper layers, thereby increasing the effective sampling depth, allowing the measurement of material inside visually opaque containers. The larger sampling area has the additional advantage of preventing sample damage by reducing the power density, as well as improving measurement accuracy by eliminating heterogeneous effect.
