ra200 raman spectrometer

product overview

ra200 is a hand-held raman spectrometer launched by lanscientific co., ltd. it adopts spatial coupling optical and electronic design, as well as scientific stoichiometry algorithm, which is easy to operate and has excellent performance. it is widely used in medicine, petroleum, chemical industry and environmental protection. food, materials, public security, maritime affairs, national defense and other fields.

the product principle

raman spectroscopy is a nondestructive analytical technique based on the interactions of photosynthetic materials. raman spectroscopy can provide detailed information on the chemical structure, phase and morphology, crystallinity, and molecular interactions of the sample.

raman is a light scattering technique. when the high-intensity incident light of a laser source is scattered by molecules, most of the scattered light has the same wavelength (color) as the incident laser, and this scattering is called rayleigh scattering. however, a very small fraction (about 1/109) of the scattered light has a different wavelength (color) than the incident light, and the change in wavelength is determined by the chemical structure of the test sample (the so-called scattered material). this part of the scattering is called raman scattering.
