Wavelength Measurement——Fiber Optic Spectrometer |
|
|
Wavelength
is the spatial period of the wave - the distance between
consecutive corresponding points of the same phase. Light wave
refers to electromagnetic spectrum, which has wavelengths in the
range of 0.1mm to 0.1 μm. The wavelength of the light wave is
the light wavelength.
CNI fiber
optic spectrometers with the characteristics of compact and
portable design, plug and play, easy operation and Spectral
Analysis 5.0 software downloads, can replace the old
spectrophotometers. They are widely used in laser wavelength and
line width measurement and also the laser excitation
fluorescence, Raman and LIBS spectrum measurement. |
