The NRS-3000 Series

The NRS-3000 Series of bench top, singly dispersive micro-Raman spectrometers are based on JASCO’s proven technology emphasizing sensitivity, reliability, and ease of operation from a PC-controlled optical system.

The innovative instrument design ensures freedom from daily adjustments and alignment. 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 that is compact enough to fit on a laboratory bench.

With superb stability and effortless software controlled optics, the NRS-3000 Series Raman systems offer performance second to none, and with no time-consuming realignment. Simply insert the sample, focus, and collect the spectrum. The integrated, automated x-y-z 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-3000 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 six lasers.

The JASCO NRS-3000 family offers a choice of systems that can exactly meet your needs, as well as your budget, and gives you the ability to upgrade for future requirements. These new spectrometers offer capabilities previously limited to complex “triply dispersive” Raman instruments.

NRS-3100

- Resolution 1 cm^-1 ((0.4 cm^-1 option))
- Optional laser wavelength range : Visible - NIR
- Spectral Range (Raman shift at 532 nm excitation): 50 to 8000 cm^-1
- CCD detector : air-cooled to -65 degree celsius

NRS-3100 The NRS-3100 features a high performance 532 nm laser, TE-cooled CCD detector and an 1800 grooves/mm holographic grating. This is an extremely cost-effective and powerful package ideally suited to many Raman applications. Laser auto-alignment and the full sample enclosure are standard features, not expensive upgrades; the optical mode and slit operations are under full software control. Or, choose from a wealth of options and accessories, including a second internal laser or up to four lasers mounted externally; up to three softwareswitched gratings; a motorized sample stage with laser auto-focus; high spectral resolution (0.4 cm-1 option), and many other options. The “hands-free” operation and ultra-stable optics designed into the NRS-3100 combined with JASCO’s fully-featured Spectra Manager™ II  software package combine to make this the easiest to use micro-Raman system available, as well as the best performing.

NRS-3300

- Resolution 1 cm^-1 (0.4cm^-1 optional)
- Optional laser wavelength range : UV-NIR
- Laser/Raman beam splitter : Dichroic mirrors and beam splitter
- Spectral Range (Raman shift at 532nm excitation): 50 to 8000 cm^-1 (10 - 8000 cm^-1 with Low wavenumber attachment)
- CCD detector : air-cooled to -75 degree celsius
- Raman Imaging System Option

NRS-3300 is a research grade instrument. the NRS-3300 offers low wavenumber Raman shift capability previously only available in complex, low throughput “triple dispersive” spectrometers with a modern, easy-touse software-controlled package. Unlike other designs that are wavelength specific, the low wavenumber ranges on the NRS series are automatically configured by the software for different excitation wavelengths from violet through deep red. Combined  with all the features expected on a confocal micro-Raman system, with a full range of options and upgrades, the NRS-3300 will form the basis of your Raman research for years to come.
