Molecular optics laser examiner MOLE

Molecular optical laser examiner (MOLE) Instrument eombining a laser excitation source with a microscope, resulting in a raman spectrum which can be used to fingerprint chemically small particles or thin films of complex compounds. 

In his Ph.D. thesis [61], Dhamelincourt detailed optical considerations for the design and implementation of a Raman microprobe and microscope, based on commercial optical microscopes, a design that was commercialized as the MOLE (Molecular Optical Laser Examiner) by Lirinord/Jobin Yvon. In this system, a beam splitter in a standard epi-illuminator (Fig. 3) was used to disentangle the incident laser beam from the Raman scattered beam.
