Renishaw inVia micro-Raman spectrometer

Instrument types

In this system samples are excited by 405, 532, 633 or 785 nm lasers. Laser spot size is ~1 ┬Ám and spectral resolution is about 1 cm-1. Signals can be measured within 100 cm-1 of the laser wavelength. Linearly and circularly polarized excitation are possible for the green (532 nm) and red (633 nm) incident beams. Confocal measurements and 2-dimensional mapping (single wavelength or full spectrum) are also possible.
