G01N21/631 - CPC Classification

Classification description:

Investigating or analysing materials by the use of optical means, i.e. using sub-millimetre waves, infrared, visible or ultraviolet light; Systems in which the material investigated is excited whereby it emits light or causes a change in wavelength of the incident light optically excited using photolysis and investigating photolysed fragments
