Raman Spectrum Solution

 

Raman Spectrum is given material molecular vibration and rotation information, different materials have different from other material characteristic spectrum - characteristic peak, which provides for the characterization and identification fingerprinting substance. 
Its application areas include chemical/biological research, environmental science, jewelry appraisal, textile industry, food safety testing, judicial authentication, pharmaceutical and medical diagnostics, geological exploration and detection of dangerous goods, etc.

 

Changchun New Industries (CNI), founded in 1996, is a manufacturer of solid-state and diode laser systems. CNI laser
features with high performance, nice reliability, and specifically designed for OEM, scientific, industrial and instrumentation use.
In addition, CNI lasers are ISO-9001, FDA, CE and RoHS certified. CNI laser can satisfy the customer’s demands of high efficiency and stability in different environments. CNI has provided lasers
to many customers at home and abroad as laser light source.
