In the chemistry, pharmaceutical, materials testing, and petrochemical industries, the ability to quickly analyze and identify a substance is key. One solution is to use a Raman spectrometer. By taking advantage of the scattering of laser light hitting a sample, a Raman spectrometer can read the subtle energy shift in the scattered light caused by the vibration of the substance undergoing analysis. Raman spectrometers typically employ diode or gas lasers of 532 or 785 nm. For applications like forensics, where samples are often contaminated, some Raman spectrometers offer wavelengths of 1064 to filter fluorescence at the cost of overall sensitivity.
Considerations for purchasing a Raman spectrometer
Detectors for Raman spectrometers include CCD arrays, InGaAs, or Ge types. Some Raman spectrometer systems are coupled with high-end microscopes for micro molecular analysis.

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

Although the RMP-510 is described as a portable Raman spectrometer, this is largely due to its robust optical design and tolerance to being transported. In fact the optical performance is close to that of a conventional bench top Raman system and offers many of the same features like interchangeable grating monochromators for a range of spectral resolutions. Spectra Manager Software simplifies data collection and analysis. Sadtler KnowItAll ™ software is included for library searching and sample database creation. Installation and training are included.... Read More |
