Laser Sources for Raman Spectroscopy |
|
CNI
specially designed lasers for Raman
applications. They have the features of narrow
spectral bandwidth, high spectral purity, high
wavelength stability, high efficiency, long
lifetime, high reliability and good beam
quality. To guarantee the stability and accuracy
of the Raman testing results, CNI provide
different kinds of wavelength and power levels
to meet customer’s practical requirements. |
