Confocal Raman Microscopy now available to users

We are pleased to announce that the Renishaw inVia Qontor Confocal Raman Microscope is operational and open for training to all nanoFAB users. The inVia Qontor Confocal Raman Microscope is a flexible Raman instrument with unique real-time focus-tracking capabilities for fast and advanced 2D/3D analysis of samples with flat, uneven, curved, or rough surfaces.

The main features include:

  • 3 lasers: 532 nm (50 mW), 633 nm (17 mW) and 785 nm (300 mW)
  • Objectives: 5X, 20X, 50X (long Working Distance), 100X
  • Minimum stage step size of 50nm
  • 2D/3D imaging
  • Spatial resolution better than 300 nm (532 nm excitation)
  • Axial resolution better than 1.5 μm
  • LiveTrack™ focus tracking technology to maintain optimum focus automatically in real time during data collection and white light video viewing
  • Macro Sampling Kit allows analysis of non-standard samples, that includes a 90° adapter to allow analysis of samples mounted at 90° to the optic axis and various holders for vials, NMR tubes, cuvettes and capillary tubes.

If you are interested to submit samples for staff analysis or get trained on the tool, please submit a “sample”  or “training” request on LMACS. If you have any questions, please contact Peng Li ( – the Characterization Group Manager.
