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.
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
In-vivo biological studies
The transportable Virsa analyser is ideal for developing clinical applications of Raman spectroscopy. It is available with a clinically ready fibre-optic probe that is suitable for research in a clinic or operating theatre. Choose the Virsa analyser to help translate Raman technology into clinical applications.
Cultural heritage and conservation
Cultural heritage artefacts are often large, immobile or too delicate to be moved. The Virsa analyser is uniquely suited for the non-destructive characterisation of such relics. Equipped with multiple laser excitation wavelengths and LiveTrack technology, the Virsa analyser can study a large number of samples with microscopic detail.
