| Description | The NRS-7500 Series Confocal Raman Microscope 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, The NRS-7500 Series Confocal Raman Microscope 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 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.
Features: - Exceptional wavenumber accuracy with a high-precision rotary-encoder direct drive mechanism
- Wide wavenumber range up to 8000 cm-1
- Automated XYZ with joystick and mouse/keyboard control
- Spectra Manager™ operating system for measurement and confocal imaging
- Low wavenumber measurement, close to the Rayleigh scatter(NRS-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) providing higher spatial resolution than conventional confocal optics, especially in the Z axis
- Patented Spatial Resolution Image (SRI) function for simultaneous observation of sample image, laser spot and aperture image

A The NRS-5500 Series Confocal Raman Microscope 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.
