NRS-5000 Series Confocal Raman Microscope

NRS Series Raman Spectrometers
NRS Series Raman Spectrometers

The NRS-5000 is a research grade confocal Raman microscope with f300 spectrograph that combines the flexibility of multiple detectors and multiple laser sources to quickly change between measurement modes for fast data acquisition to reduce experimental time. A number of unique technologies have been developed to improve measurement efficiency; these include

  • QRi for very fast imaging with high resolution auto-stage
  • SPRIntS for fast mapping without the necessity of moving the sample stage
  • SRI (Spatial Resolution Image) for simultaneously viewing the sample image and laser spot.
  • DSF (Dual Spatial Filtration) which optimizes confocal focusing of the image produced by the objective lens  to reduce aberration and improve spatial resolution and reduce the effects of matrix fluorescence.

A rigid honeycomb optical base is the foundation of the instrument ensuring alignment and stability. The laser(s), microscope, software-switched optics and a unique aberration-corrected polychromator with CCD or InGaAs detectors provide an integrated compact package that is . Operator safety (Class 1 laser safety) is maintained by a fully enclosed automated sample chamber door. This provides a 120 degree opening for the user to freely access the sample stage and objectives revolver when setting up the experiment.

A high resolution color CCD viewing system with synchronized image capture and spectrum measurement enables accurate sample identification and positioning. All data is recorded in the Spectra Manager™ imaging application. An automated 4 position grating selector, 2 internally mounted detectors and up to 8 lasers ranging from the UV through the NIR. The NRS-5000 is software controlled for maximum flexibility so that once the sample is loaded onto the sampling stage the user has complete control under conditions of class 1 laser safety.
