拉曼光譜儀的特點：

此高性能科研級顯微拉曼光譜儀（high performenced Raman microscopy）具有如下特點：

Research-grade model assuring high spectral quality
Exceptional wavenumber accuracy with a high-precision rotary-encoder direct drive mechanism
Low wavenumber measurement （NRS-5200/7200）
Auto-alignment of microscope laser introduction optics and Raman scattering light path
Wavenumber calibration using an integrated Ne lamp
Unique Dual Spatial Filter （DSF） for higher spatial resolution than conventional confocal optics
Patented Spatial Resolution Image （SRI） function for simultaneous observation of sample image,
laser spot and aperture image
Full range of options including macro-Raman measurement unit and fiber optic probes

拉曼光譜儀NRS系列的具體型號及參數(shù)如下所示：

*1 At 532 nm excitation wavelength with the standard rejection filter.
*2 At 532 nm excitation wavelength with the low wavenumber attachment.
*3 UV laser, edge filter for UV laser, and UV objectives are additionally required.
*4 One dichroic mirror can be mounted when either the UV upgrade or the SPRIntS imaging option is configured.
No dichroic mirror can be utilized when both the UV upgrade and the SPRIntS imaging options are fitted.
*5 The specifications are partially different from the standard model when UV laser is used.
*6 The laser may not be internally mounted due to the specification of the laser.
*7 Autostage imaging option is required.
*8 SPRIntS imaging option or autostage imaging option is required.
*9 Raman system must be placed on anti-vibration or equivalent table.
