Renishaw inVia Raman Microscope (325, 442 and 514 nm)

Raman inVia Spectrometer

The inVia is a Raman spectrometer coupled to a microscope. The microscope focuses a laser source onto specific areas of a sample then collects the light scattered off the surface of the sample and directs it through a Raman spectrometer.

Capabilities of the inVia Raman Microscope:

  • Standard set-up: Raman using 514 nm (green) Argon ion laser with 1800 l/mm grating.
  • Raman using 325 nm or 442 nm - email the lab 24 hours before your booking.
  • Mapping to 500 nm resolution using 514nm laser.
  • Standard mode laser spot size is around 1.5 micron at 50x magnification. Smaller spot size of 0.5 micron is possible when using confocal mode.
  • Photoluminescence at 325 nm - email the lab 24 hours before your booking.
  • Near excitation measurements, down to ~8cm-1 - email the lab 24 hours before your booking.
  • Higher spectral resolution is available for the 514 nm laser by using a the 2400 or 3000 l/mm gratings (see image below) - email the lab 24 hours before your booking.
  • An optic fibre probe is available for samples that don't fit under the microscope - email the lab 24 hours before your booking.

Applications of this instrument:

  • Ideal for identification and structural studies of most mineral and inorganic samples eg.geological samples, semiconductors
  • Organic, polymer and inorganic samples can be measured and frequently identified using a library database. If fluorescence is a problem using the 514nm source, then the 633 nm or 785 nm source may be a better choice (see Renishaw inVia 2¬†or PerkinElmer Raman Microscope).
  • Measurement of biological samples at low power (around 0.1 mW).
