System description

  • The standard Class 1 safety cabinet more commonly associated with high-end Raman systems.
  • The automatic XYZ stage is used for confocal imaging with X/Y spatial resolution to 1 µm (Z=1.5 µm). Spectra Manager™ Suite with the Imaging Analysis application is used to collect a three dimensional image of the sample which can be rotated and viewed from any angle. The image map is created using peak data corresponding to key functional groups and analysis of multiple peaks can be combined to create powerful data images.
  • The microscope has a completely rigid structure to prevent flexing and is not built around an optical microscope.he microscope has a completely rigid structure to prevent flexing and is not built around an optical microscope.
    Switching between observation and measurement modes is completely automatic and can be done with the safety cabinet closed.

Standard Configuration
532/785nm Lasers with Matching Edge Filters

The NRS-4500 offers several standard configurations including the typical 633nm single laser or 532/785nm laser combination with matching notch or edge filters, with an option for a third laser which can be mounted internally or externally. Observation of the laser spot ensures perfect alignment of the target sample position and provides an indication of surface roughness. All laser wavelengths are selected in the software and once selected, the optical system (including the laser) is automatically aligned for optimal throughput and resolution. Four software selectable gratings control the spectral range and resolution from 8000 to 100 cm-1 (8000 to 50 cm-1 as an option). The grating direct drive system includes a rotary encoder to ensure excellent wavelength reproducibility ±0.2cm-1.

Fluorescence Rejection
457nm Laser and Patented Fluorescence Rejection Algorithm

JASCO has developed new and novel (patented) mechanisms to deal with sample fluorescence. As with other Raman systems, we can utilize laser wavelengths of 785 nm and up to 1064 nm, but we have recently incorporated a 457 nm laser that offers significantly higher Raman signal, improved spatial resolution and much lower fluorescence for many different sample types. Selecting a different excitation laser wavelength is only one of the ways the NRS-4500 minimizes fluorescence interference. The Fluorescence Rejection algorithm (patented) included in the Spectra Manager™ can effectively remove or minimize fluorescence regardless of the laser wavelength used either at the time of measurement or during post-processing.

  • Flexible Sampling Options

    With a choice of refractive objectives, both micro and macro measurements are possible as well as options for long working distance objectives for heating/cooling stages and other sampling accessories. The NRS-4500 can be used with either a manual sample stage or the PC-controlled, automated XYZ confocal mapping stage. A fiber probe can be added for external measurement.

  • Powerful ‘UserAssist’ Control for Experienced Spectroscopists and New Users

    The ‘UserAssist’ software aids the user in setting up the NRS-4500 for sample measurement; a simple sequence guide takes you through setup and optimization of measurement parameters with helpful advice and tips, such as a warning if you have the laser intensity set too high. When each of the parameters has been set, the NRS-4500 automatically selects the laser and matching notch filter, the grating for the appropriate resolution, focuses on the sample and then the spectral measurement is performed.

  • ‘Simple Search’ Function

    The new ‘Simple Search’ function is used with the automated XYZ stage. A new algorithm developed by JASCO (patent pending) analyzes the microscopic image and automatically selects measurement position(s) based on size, contrast and/or color of the target material. The user simply clicks the measurement button to execute spectral measurements of the desired sample positions.

  • Chemical Image Identification and Functional Groups Registry

    To provide faster Raman image processing, the Imaging Analysis software includes a ‘Registry’ of possible functional groups or other relevant compound information based on peak height or area calculations. After peak height or area calculation is developed, it can be saved to the Registry for future analysis use. The registry includes the peak calculation information and a ‘label’ describing the relevant vibrational motion. Image maps can be developed from mapping data simply by clicking on the desired, registered calculation to obtain a false color image of the peak intensity data for the registered calculation.

Overview

The NRS Series for confocal Raman imaging microscopy includes three different optical configurations; the easy to use, yet powerful NRS-4500, with up to three laser wavelengths (from a wide range of visible to NIR) including the common dual laser 532/785nm configuration).

System description

We developed a number of key technologies to improve measurement efficiency; these include DSF (Dual Spatial Filtration) which optimizes confocal focusing of the objective to reduce aberration and improve spatial resolution, SPRIntS for fast mapping without the necessity of moving the sample stage and SRI (Spatial Resolution Image) for simultaneously viewing the sample image and laser spot.We developed a number of key technologies to improve measurement efficiency; these include DSF (Dual Spatial Filtration) which optimizes confocal focusing of the objective to reduce aberration and improve spatial resolution, SPRIntS for fast mapping without the necessity of moving the sample stage and SRI (Spatial Resolution Image) for simultaneously viewing the sample image and laser spot.

A rigid honeycomb optical base is the foundation of the instrument ensuring alignment and stability. The laser(s), 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. Operator safety (Class 1 laser safety) is maintained by a fully enclosed automated sample chamber door. This provides a 120 degree opening for the user to freely access the sample stage and objectives turret when setting up the experiment.

A high resolution color CCD viewing system with synchronized image capture and spectrum measurement enables accurate sample identification and positioning. The data is recorded in the Spectra Manager™ imaging application program and stored in the data file structure for easy reference. 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. All optical components are software controlled for maximum flexibility with minimum user interaction once the sample is loaded.
