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
