Spectrometer

Spectroscopy is a branch of optics, studying the generation of spectrum of various substances and its interaction with materials. Spectroscopy technology is not only a scientific tool, it also provides an important method of qualitative and quantitative analysis in the chemical analysis. Spectroscopy technology works by measuring the light intensity of ultraviolet, visible, near infrared and infrared wavelengths, is widely used in scientific research, teaching, industrial and many other fields.To create a one-stop shopping service, CNI provide following three types of Spectrum Analyzers for meeting customers` need. CNI offers Laser, spectrometer, software analysis and other products, also provides customized products according to customers` demands
