NRS and portable series Raman Spectrometers

The NRS 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 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 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.

NRS-5000 and NRS-7000 Series Raman

The performance and functions expected on a micro-Raman spectrometer are all provided with the NRS-5000 and 7000 series Raman systems, assuring consistent performance for rapid acquisition of high quality data with automated system control and minimal optical adjustments.

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.

RMP-300 series Portable Raman Spectrometer

The RMP-300 Series portable Raman spectrometer system incorporates a fiber optic probe with a small X-Y-Z stage, compact laser, a high-throughput spectrograph and Peltier-cooled CCD detector. No special utilities such as coolants are required allowing the system to be used almost anywhere. The flexibility of optical fiber coupling enables remote measurements by locating the probe right at the sample. The fiber optic probe features an integrated CCD video camera for sample positioning and capturing of digital sample images. All operations are performed by the dedicated software package based on JASCO Spectra Manager™ II.

The RMP-300 Series consists of six models, the RMP-310, 315, 320, 325, 330, and 335, ranging from small, portable units suitable for in-situ measurements to research-grade systems to provide capabilities for a wide range of application requirements.

The RMP-300 system is controlled using Spectra Manager™ II, JASCO's powerful Windows based cross-platform spectroscopy software package. The system is capable of both laboratory work and on-site measurements in the fields of process control, QC, forensics, art conservation and mineralogy.
