NRS-7000 series Raman


The NRS-7000 Flagship models

The innovative instrument design ensures freedom from daily adjustments and alignment.

System description

A specially designed honeycomb optical base plate is the foundation for the entire instrument guaranteeing alignment and stability. The laser(s), enclosed microscope, software-switched optics and a unique aberration-corrected polychromator with CCD detector provide an integrated package compact enough to fit on a laboratory bench.A specially designed honeycomb optical base plate is the foundation for the entire instrument guaranteeing alignment and stability. The laser(s), enclosed microscope, software-switched optics and a unique aberration-corrected polychromator with CCD detector provide an integrated package compact enough to fit on a laboratory bench.

With superb stability and effortless software controlled optics, the NRS Series Raman systems offer performance second to none, with no time-consuming realignment. Simply insert the sample, focus, and collect the spectrum. The integrated, automated XYZ mapping stage with auto-focusing option allows full PC control. Complete operator safety is maintained by the fully enclosed automated sample chamber door which provides a 120 degree opening to allow full microscope access.

All NRS Series Raman instruments include a color CCD sample viewing system with image capture capability. For additional flexibility, a trinocular microscope attachment can be added for direct binocular viewing. Utilizing the same basic optical system, we’ve designed a family of micro-Raman spectrometers that offer a range of capabilities from simple, single laser, single grating instruments to advanced research grade systems with low wave number measurement, wavelength extension from the deep UV to NIR, and the ability to use or add up to 6 lasers.

For application expansion, an automated multi-grating turret, 2 internally mounted detectors and a maximum of 8 lasers ranging from the UV through the NIR are capable of integration with the instrument system. All optical components are PC controlled for maximum flexibility with minimum user interaction.

  • ● Research-grade model assuring high spectral quality

  • ● Low wavenumber measurement (NRS-5600/7600)

  • ● Auto-alignment of microscope laser introduction optics and Raman scattering light path
  • ● Wavenumber calibration using an internal 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

Overview

The NRS Series for confocal Raman imaging microscopy includes three different optical configurations; the easy to use, yet powerful NRS-4500, with up to three laser wavelengths (from a wide range of visible to NIR) including the common dual laser 532/785nm configuration). The sophisticated NRS-5000 Series, with 300mm spectrograph, offering higher spectral and spatial resolution with the use of dual spatial filtration (DSF) and the NRS-7000 Series with 500mm spectrograph and poly-dispersive options. Both the NRS-5000 and NRS-7000 can be configured with up to 8 lasers (9 wavelengths). All models include Class 1 laser safety as standard and share the same comprehensive Spectra Manager™ Suite of measurement and micro-imaging software.
  • NRS-7500

    Maximum Resolution 0.7 cm -1/ 0.3 cm -1 (optional)
    Measurement Range 50 to 8000 cm -1

    NRS-7600

    Maximum Resolution 0.7 cm -1/ 0.3 cm -1 (optional)
    Measurement Range 5 to 8000 cm -1

System Features NRS-4500/5000/7000 series

  • ● High accuracy spectral resolution, with the use of rotary encoders for the grating drive mechanism to as little as 0.3cm-1 per pixel
  • ● High spatial resolution with 0.1µm step, using the automated XYX stage (actual resolution depends on laser wavelength and objective magnification and N.A.)
  • ● QRi (Quick Raman imaging) – a combination of EMCCD with an ultra-fast XYZ stage giving 0.1µm step resolution QRI increases the data acquisition speed by up to 50x compared with a conventional mapping stage and also offers a significant improvement in sensitivity. Available on all models
  • ● SPRinTS (Software Programmable Raman Integration Speed) which uses Vertiscan to scan the laser through the objective to map samples that are likely to move using a conventional mapping stage, such as liquids and suspensions. Available on the NRS-5000 and NRS-7000 models only
  • ● Long working distance stage and objectives, for larger samples and temperature control and high pressure accessories
  • ● Optional fiber probe interface for external measurements
  • ● Macro objective for measurement of powders and liquids
  • ● Patented Fluorescence Rejection,  an algorithm to reduce or eliminate fluorescence an enhance Raman measurement. Available on all models
  • ● Spectra Manager™ Imaging Suite with KnowItAll®, for comprehensive measurement, analysis and reporting. The cross platform software includes the same feature for all NRS models with many options for chemometrics, spectral analysis, etc.

SKANDINAVISKA GENETEC AB

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop: genetec.se
