HORIBA LabRAM Soleil™ High-Resolution, Ultra-Sensitive Intelligent Raman Imaging Microscope

Overview

The HORIBA LabRAM Soleil™ is a state-of-the-art confocal micro-Raman imaging microscope engineered for high-resolution, ultra-sensitive vibrational spectroscopic analysis at the sub-micron scale. Based on confocal optical architecture with all-reflective, broadband dielectric mirror optics, it delivers exceptional light throughput and spectral fidelity across UV–NIR excitation ranges (325 nm to 785 nm). Its core measurement principle relies on inelastic scattering of monochromatic laser light—Raman scattering—enabling non-destructive, label-free chemical identification, molecular conformational analysis, stress/strain mapping, and phase distribution quantification in heterogeneous solid, thin-film, and biological samples. Designed for 24/7 unattended operation in regulated and research environments alike, the LabRAM Soleil™ integrates advanced automation, thermal and mechanical stability, and Class 1 laser safety compliance—making it suitable for routine QC labs, academic core facilities, and industrial R&D centers requiring trace-level detection, nanoscale spatial discrimination, and reproducible hyperspectral data acquisition.

Key Features

• Compact footprint (<1 m²) with integrated Class 1 laser-safe enclosure (444 × 509 × 337 mm sample chamber)
• Automated optical alignment via Fast Alignment™ technology (<15 s full path realignment using built-in PSD sensor)
• Four motorized gratings switchable in <60 s; TurboDrive™ closed-loop grating actuation at up to 400 nm/s
• SmartSampling™ adaptive acquisition algorithm prioritizes spectrally informative pixels—reducing imaging time from hours to minutes
• QScan™ vector-based laser sheet scanning enables true 3D confocal Raman tomography without physical Z-stage movement
• ViewSharp™ rapid 3D surface topography integration with simultaneous Raman mapping
• Multi-modal optical microscopy: brightfield, darkfield, epifluorescence, phase contrast, and DIC
• Low-wavenumber capability down to <5 cm⁻¹ (standard configuration: <30 cm⁻¹)
• Up to four internal lasers (325, 532, 638, 785 nm); six computer-controlled notch/edge filters
• Nano-Raman compatibility: seamless coupling with AFM and SEM for TERS, nano-PL, and cathodoluminescence

Sample Compatibility & Compliance

The LabRAM Soleil™ supports diverse sample types—including powders, polymers, semiconductors, pharmaceutical tablets, biological tissues, 2D materials, and geological specimens—without requirement for conductive coating or vacuum. Its large chamber accommodates standard petri dishes, wafer carriers (up to 200 mm), and custom fixtures. The system complies with IEC 60825-1:2014 for Class 1 laser safety under normal operating conditions. Optical and spectral performance meets ISO 17025 requirements for accredited testing laboratories. For regulated industries, hardware and software design support audit-ready workflows aligned with FDA 21 CFR Part 11, EU Annex 11, and GLP/GMP documentation standards—including electronic signatures, user access control, and full audit trail logging via ProtectionPlus™.

Software & Data Management

LabSpec 6 software provides an application-driven interface with customizable dashboards, wizard-guided workflows (EasyImage™), and embedded multivariate analysis tools. MVAPlus™ implements PCA, cluster analysis, and spectral unmixing algorithms optimized for datasets exceeding one million spectra. ParticuleFinder™ automates particle detection, morphological classification (size, aspect ratio, convexity), and chemical identification in heterogeneous mixtures—delivering statistically robust reports within seconds. All spectral acquisitions include metadata stamping (laser power, objective ID, grating position, ambient temperature/humidity), ensuring full traceability. Data export supports HDF5, ASCII, and vendor-neutral JCAMP-DX formats. Remote diagnostics and firmware updates are supported via secure HTTPS channel.
