Speed, sensitivity and resolution are some of the characteristics that can be used to identify a high-quality Raman microscope.

Raman spectroscopy enables qualitative and quantitative analysis of chemical components in a sample without requiring specialized sample preparation or risking damage to the sample. Confocal Raman microscopy additionally makes it possible to monitor the spatial distribution of chemical components and properties. Raman microscopy can be combined with other techniques in order to gain additional information on the sample, such as its surface structure. Because of the huge number of available systems, the choice of a good Raman microscope is often difficult.

This WhitePaper gives five criteria for choosing a high-quality Raman microscope. Additionally, correlative Raman techniques are illustrated using examples from various fields of application.
