The laser are an inherently pure source of light. The purity of the laser can be improved the purity of any other light source. Therefore the laser is a very useful source for spectroscopy.

BeamQ miniature fiber spectrometer are used in many applications:

Radiation / light color performance
UV/VIS/NIR transmittance absorption
Light reflection
Color analysis
Fruit vegetables
Food safety
Laser analysis
Thin film optics
Fluorescence measurement
