Raman spectroscopy has become a critical tool in materials science, chemistry, nanotechnology, forensics, and life sciences, providing detailed insights into molecular vibrations, crystal structures, and chemical compositions. To fully exploit the capabilities of Raman instruments, researchers require advanced software to acquire, process, and interpret spectral data. WiRE™ (Windows-based Raman Environment), developed by Renishaw, is the primary software package used with Renishaw Raman spectrometers. It offers a complete solution for data acquisition, spectral analysis, mapping, imaging, and reporting.

WiRE is known for its deep integration with Renishaw’s hardware systems (such as the inVia™ Raman microscope), providing real-time control of experimental conditions and seamless execution of complex Raman workflows. Its intuitive interface, automation capabilities, and high-level data processing tools make it a favorite among both experienced spectroscopists and new users.

Core Features and Spectral Capabilities

WiRE supports the entire Raman workflow—from laser setup to data export. Its main features include:

• Spectral Acquisition: Real-time, multi-point, and time-series acquisition with customizable laser settings, integration time, filters, and gratings.

• Data Processing: Baseline correction, smoothing, cosmic ray removal, normalization, and derivative transformation.

• Peak Analysis: Automated peak picking, band fitting, Lorentzian/Gaussian modeling, and area calculations.

• Spectral Library Matching: Identifying unknowns using custom or built-in Raman libraries.

• 2D and 3D Raman Imaging: Full spatial-spectral mapping with chemical component analysis, false-color visualization, and surface plotting.

• Time-resolved Raman: Dynamic tracking of chemical or structural changes over time, ideal for kinetics studies.

The software handles large datasets efficiently, allowing users to visualize hundreds or thousands of spectra from Raman maps and extract meaningful patterns or material distributions.

Applications in Research and Industry

WiRE is extensively used in both fundamental research and applied materials characterization, including:

• Nanomaterials and 2D materials: Layer counting in graphene or MoS₂, strain and doping analysis.

• Semiconductors: Identifying phase transitions, stress/strain mapping, and crystallinity studies.

• Pharmaceuticals: Polymorph detection, component identification in tablets, and distribution studies.

• Polymers and composites: Mapping filler distribution, degradation tracking, and additive identification.

• Catalysts and coatings: Monitoring reaction intermediates or spatial distribution of active phases.

For example, a materials scientist studying SbSI nanowires or GO-based composites can use WiRE to confirm molecular bonding, detect phase changes, and map component distribution within the sample.

Advanced Tools and Automation

WiRE includes several high-level modules and options to enhance productivity and precision:

• AutoFocus and AutoAlign: Automated sample focusing and alignment for reproducible results.

• XYZ mapping and depth profiling: 3D chemical imaging with micrometer resolution.

• Correlative Imaging: Integration with SEM, AFM, and fluorescence microscopy for multi-modal analysis.

• Custom scripting and automation: Users can create macros and scripts to automate measurements, ideal for high-throughput environments.

• TrueSurface™ module: For topographic Raman imaging on rough or curved samples using profilometry alignment.

Users can generate chemical images, export maps as videos or images, and create comprehensive reports directly from within the software.

Benefits for Researchers and Analysts

• Intuitive user interface: Easy to learn, even for new users; supports advanced features for experts.

• Hardware-software integration: Optimized for Renishaw systems, ensuring speed and precision.

• High-resolution mapping: Capable of sub-micron spatial resolution with rich spectral data.

• Real-time analysis: View results and adjust parameters during acquisition.

• Reliable data integrity: Audit trails, metadata storage, and full export options for compliance.
