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.
- 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).
