Confocal Raman Microscope

NRS-7000 Series

NRS-7000 Series Raman
NRS-7000 Series Raman with f500 spectrograph

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 a 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 an auto-focusing option allows full PC control. Complete operator safety is maintained by the fully enclosed automated sample chamber door which provides a 120° 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.
