XperRam 200
Excellent Resolution
Outstanding Repeatability
High throughput using Holographic Transmissive Grating
Extendable / Customizable
200μm x 200μm Image fast Scanning & 2D Mapping (x 40 objective)
FEATURES:
  • LASER SCANNER
    - Excellent resolution & repeatability -
    resolution < 0.02 um & repeatability < 0.1 μm.
    - Large area Raman imaging -
    scan area exceeding 200 x 200 μm using a 40X, NA=0.75 objective
    - Diffraction limited laser spot -
    over the scan area
  • Lens based VPHG spectrometer
    - High efficiency and small polarization dependence can be achieved
    using Holographic Transmissive Grating
  • Average mode
    - High Speed in averaging mode –
    Acquire a single Raman spectrum over the 200 x 200 μm area in just 4 seconds
    - Minimum CCD readout-noise -
    CCD acquires one Raman spectrum while the laser scans over the area, thus reducing the CCD readout-noise greatly compared to conventional 2D Raman mapping method.
    - Useful for quick quantitative analysis of the analytes on thin samples -
    thin films or nanoparticles on a glass slide
