inVia: spectral flexibility

You can configure your inVia so that it is ideal for analysing your particular samples. Choose the best combinations of lasers, detectors, filters and gratings, so you get the best Raman data in the shortest possible time.

Multiple lasers, with easy switching

SPD_multiple_laserinVia supports multiple lasers for Raman spectroscopy, with easy automated computer-controlled switching between them. You can change excitation wavelength rapidly and reliably, and quickly determine the best configurations to get great data from all your samples.  

In addition to a wide range of visible excitation lasers, it can also support deep UV (down to 229 nm), near UV (e.g. 325 nm) and infrared (e.g. 1064 nm) lasers. These lasers have direct optical coupling (no optical fibres) and wavelength-optimised laser paths. This maximises the laser power delivered to the sample, reducing your spectrum acquisition times.

More than 20 excitation wavelengths are available, enabling you to choose the lasers that are best for your particular applications.

inVia normally accommodates two or three lasers as standard, but Renishaw can configure your inVia to use as many lasers as you need.

Choice of Rayleigh filters and diffraction gratings

inVia's motorised component mounts enable you to switch between up to four different Rayleigh filter sets, and up to two diffraction gratings, without the need for manual intervention.

inVia's Rayleigh filters and diffraction gratings use Renishaw's kinematic mounts which are easy to remove and relocate with very high accuracy. This gives you the flexibility to swap gratings and filters if you need to support a very large number of configurations. inVia handles the complexity of the change, applying the appropriate calibration settings and adjusting the internal optics to their optimised positions.

Multiple detectors

Andor InGaAs array detectorA single detector is ideal for many users, but if you need more, inVia can support up to four. For example, you may wish to add an electron multiplied (EM) detector or an InGaAs array for efficient detection in the infrared when using 1064 nm excitation.
