Virsa™ Raman Analyser

The world's only Raman system with remote probes capable of automatic
focus-tracking.

The Virsa fibre-optic-coupled Raman analyser enables you to take your spectroscopic analysis away from the confines of the laboratory microscope to new samples and environments.

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.

Capabilities

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

Flexibilty

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.

LiveTrack technology

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.

Monitor software

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.

Applications

Coatings

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.

Nanotechnology

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.
