The RM5 Raman Microscope

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

Features of the RM5 Raman Microscope

  • Truly confocal – With a variable slit and multiple position adjustable pinholes for higher image definition, better fluorescence rejection, and application optimization
  • Integrated narrowband Raman lasers – Up to three computer-controlled lasers are available for user-friendliness, improved stability, and decreased footprint
  • 5-Position grating turret – For an unmatched spectral resolution of <0.3 cm-1 and optimization over the entire spectral range, from <50 cm-1 to 15,000 cm-1
  • Integrated detectors – Up to two integrated detectors, such as EMCCD, high-efficiency CCD, and InGaAs arrays for increased speed, low noise, high sensitivity, and extensive spectral range

Product Description

The Raman microscope builds on the expertise of strong and proven building blocks, integrated with advanced optical design considerations. It also concentrates on speed, accuracy, and function. The outcome is a modern Raman microscope that stands independently in both specifications and user-friendliness.
