High-performance, transportable Raman spectroscopy for in-field and laboratory applications
Product Overview
The Virsa Raman analyser is a fiber-optic-coupled, transportable Raman system that delivers research-grade performance wherever you need it. Equipped with microscope-resolution and bulk-sampling probes, it enables both macro and micro Raman analysis of samples in situ—whether large, immovable, or contained within vessels. High spectral sensitivity, excellent resolution and precision encoders ensure reliable data acquisition in the field or the lab
Key Features
- Transportable, fiber-optic-based Raman spectrometer for on-site analysis of large or fixed samples
- Exchangeable microscope-resolution probes for chemical imaging of heterogeneous materials
- Support for multiple excitation wavelengths (532 nm, 660 nm, 785 nm) to avoid fluorescence and optimize contrast
- High-precision motorized grating and optical encoders for full-range, artefact-free spectra across UV–NIR
- Simultaneous support for up to four probes, with kinematic mounts for rapid switching
- LiveTrack focus-tracking option for real-time maintenance of focus on uneven or moving surfaces
- Compatible with WiRE software for automated acquisition, mapping, spectral libraries and real-time process monitoring

Applications
- Chemical & Pharmaceutical: Real-time monitoring of reaction kinetics and phase changes using immersion probes and high-temperature cells.
- Energy & Materials: Roll-to-roll quality control of graphene and thin films on metal foils, leveraging LiveTrack focus-tracking to maintain focus on rough, moving substrates.
- Manufacturing & Quality Assurance: In-field analysis of coatings, composites and large assemblies (e.g., turbine blades, solar modules) without sample removal.
- Art & Heritage Conservation: Non-destructive pigment mapping and layer analysis of paintings, monuments and archaeological artifacts.
- Environmental & Forensic: On-site detection of pollutants, microplastics and trace contaminants in water, soil and industrial effluents.
