Confocal Raman Imaging Microscopes
The NRS Series of confocal Raman imaging microscopes includes three different optical configurations; the easy to use, yet powerful NRS-4500, with up to three laser wavelengths (wide range, from visible to NIR) including the common dual laser 532 nm/785 nm configuration. The sophisticated NRS-5000 Series, with a 300 mm spectrograph, offers higher spectral and spatial resolution with the use of dual spatial filtration (DSF), and the NRS-7000 Series with 500 mm spectrograph and poly-dispersive options. Both the NRS-5000 and NRS-7000 can be configured with up to 8 lasers (9 wavelengths). All models include Class 1 laser safety as standard and share the same comprehensive Spectra Manager™ Suite of measurement and micro-imaging software.
System Features
- High accuracy spectral resolution, with the use of rotary encoders for the grating drive mechanism to as little as 0.3cm-1 per pixel
- High spatial resolution with 0.1µm step, using the automated XYX stage (actual resolution depends on laser wavelength and objective magnification and N.A.)
- QRI (Quick Raman Imaging) – a combination of EMCCD with an ultra-fast XYZ stage giving 0.1µm step resolution QRI increases the data acquisition speed by up to 50x compared with a conventional mapping stage and also offers a significant improvement in sensitivity. Available on all models
- Advanced Sample Search – identify target components based on size, shape, color, and contrast
- IQ Frame™ – register and find the exact measurement positions every time in IR and Raman microscopy
- SSI (Surface Scan Imaging) uses AI algorithms for quick analysis of rough or uneven samples for fast measurement
- MCR for component imaging using real-time chemometrics
- Advanced Spectral Search for real-time component identification
- SPRinTS (Software Programmable Raman Integration Speed) uses Vertiscan to scan the laser through the objective to map samples that are likely to move using a conventional mapping stage, such as liquids and suspensions. Available on the NRS-5000 and NRS-7000 models only
- Long working distance stage and objectives, for larger samples and temperature control and high-pressure accessories
- Optional fiber probe interface for external measurements
- Macro objective for measurement of powders and liquids
- Patented Fluorescence Rejection, an algorithm to reduce or eliminate fluorescence and enhance Raman measurement. Available on all models
- Spectra Manager™ Imaging Suite with KnowItAll®, for comprehensive measurement, analysis, and reporting. The cross-platform software includes the same feature for all NRS models with many options for chemometrics, spectral analysis, etc.
