The atomic force microscope (AFM) is one kind of scanning probe microscopes (SPM). SPMs are designed to measure local properties, such as height, friction, magnetism, with a probe. To acquire an image, the SPM raster-scans the probe over a small area of the sample, measuring the local property simultaneously.

Photoluminescence (PL) spectroscopy is a non-contact, non-destructive method of probing the electronic structure of materials. It is caused by a two step photon absorption-emission process involving the electronic states of the material. The emission of light through this process is photoluminescence. By combining Raman analysis with PL detection, it is possible to characterise both the vibrational and electronic properties of materials on a single bench top platform
Combined Raman-PL systems allow confocal mapping capabilities with sub-micron spatial resolution. A wide range of excitation wavelengths is possible, from the UV to NIR, allowing control of the penetration depth into the material, and thus, control of the volume sampled. Systems can be configured with different detectors such as CCD and InGaAs, which provide high sensitivity detection from the UV out to 1.5 µm and beyond. Temperature stages can be used in combination with the Raman-PL systems allowing analysis of samples at temperatures down to 4.2K.
