RM5 Raman Microscope

  • Truly Confocal – with variable slit and multiple position adjustable pinhole for higher image definition, better fluorescence rejection and application optimisation
  • Integrated Narrowband Raman Lasers – up to 3 computer controlled lasers for ease of use, enhanced stability and reduced footprint
  • 5-Position Grating Turret – for unrivalled spectral resolution of <0.3 cm-1 and optimisation over the full spectral range <50 cm-1 – 15,000 cm-1
  • Integrated Detectors – up to 2, including high efficiency CCD, EMCCD and InGaAs arrays for low noise, increased speed, high sensitivity and wide spectral range

Product Description

The RM5 is a compact and fully automated Raman microscope for analytical and research purposes. The truly confocal design of the RM5 is unique to the market and offers uncompromised spectral resolution, spatial resolution, and sensitivity.

The RM5 builds on the expertise of robust and proven building blocks, combined with modern optical design considerations; and a focus on function, precision and speed. The result is a modern Raman microscope that stands alone in both specifications and ease of use.

  • Internal Standards and Auto-Calibration – to ensure the highest quality data at all times
  • 4-Position Raman Filter Turret – fully automated notch and edge filters to match the Raman range to excitation laser wavelength
  • Ramacle® Software – one powerful software package for complete system control, data acquisition, analysis and ease of upgrade
  • High Performance Microscope – compatible with all the latest accessories

Ramacle is an exceptional software package written for complete instrument control and data handling on the RM5 system. Ramacle controls all RM5 functions with a straightforward design concept. It focuses on all modern Raman spectroscopy applications, while at the same time, providing a user-friendly interface with ‘ready to publish’ outputs.

RM5 Raman Microscope Software

The software provides control, visualisation, data acquisition, analysis and presentation of the RM5 whether it is used for generating Raman spectra or with advanced upgrades such as  Raman mapping.

Ramacle enables sample visualisation, live signal monitoring and parameter optimisation before every measurement. The instrument status and signal are displayed and constantly updated during measurements.

RM5 Raman Microscope Software

Data generated by Ramacle have a proprietary file format. This contains all measurement and instrumental properties, allowing the user to retrieve important information whenever needed and ensures data traceability. Simple input and output functions provide the required compatibility with third party data analysis or presentation packages.

KnowItAllTM Raman Identification Pro spectral library is available for material identification and advanced analysis. Data acquisition methods such as single measurements, multiple and  accumulated scans, kinetic scans and generation of maps (accessory dependent) are implemented by intuitive and in user-friendly wizards.
