Virsa™ Raman analyser
The world's only Raman system with remote probes capable of automatic focus-tracking.
Using our LiveTrack™ focus-tracking technology and Monitor™ software, the Virsa system can easily perform real-time analysis on samples that have irregular surfaces, are changing shape as they undergo phase changes, and that move, such as those on production lines.
- High performance portable fibre coupled Raman system
- High spatial resolution x/y <1 µm, z <2 µm
- Live white light sample viewing for accurate sample targeting
- Motorised x/y/z stack that enables accurate objective positioning for single point or mapping purposes
- Work with objective lens pointing downwards or horizontally
This versatile system has a modest footprint measuring just 543 mm x 436 mm x 178 mm. It can be used on a bench or mounted in an industry-standard 19" rack. This makes it ideal for researchers wanting to expand the application of Raman beyond traditional laboratory-based microscope systems.
The Virsa system uses fibre-optic probes enabling you to analyse large, uneven, moving, or chemically-changing samples. The probes incorporate Renishaw's LiveTrack focus-tracking technology which automatically keeps samples in focus, ensuring you get high-quality Raman data.
The Virsa system's software incorporates reaction monitoring allowing you to capture, analyse, and display data dynamically and in real time as it makes measurements at up to 8 times per second. This makes it especially suited for routine measurements on complex samples or processes.
Large, curved samples are a particular challenge for Raman analysis. LiveTrack focus-tracking is ideal for analysing complex surfaces such as this blade from a gas turbine engine. We were able to accurately measure the uniformity of the zirconia coating which prevents oxidation and corrosion.
In this example we analysed a graphene film grown on a copper foil substrate, such as is used for reel-to-reel graphene production. Graphene, being so thin, needs an efficient high-aperture lens for Raman analysis. Our results revealed the topography of the copper and the non-uniform distribution of the graphene.
