MR-532A Micro Raman Spectrometer

Product Introduction

The MR-532A is HM Instruments' entry-level micro Raman spectrometer, engineered to make professional-grade molecular analysis accessible to a broad range of laboratories. Built around a 532 nm excitation laser and the Hamamatsu 11639 CMOS linear array detector, this system combines proven optical components with an intuitive manual stage to deliver a straightforward Raman measurement experience without unnecessary complexity.

The 532 nm wavelength provides strong Raman scattering intensity, making the MR-532A particularly effective for analyzing inorganic materials, carbon-based nanomaterials, and crystalline minerals where fluorescence interference is minimal. With a wavenumber range of 200–4000 cm⁻¹ and spectral resolution of 7 cm⁻¹, the system covers the fingerprint and stretching vibration regions that contain the most diagnostically useful molecular information. The rack-mounted microscope with 5x, 20x, 50x, and 100x objectives enables analysis at spot sizes down to 25 μm, supporting investigations from bulk survey to single-particle characterization.

For laboratories seeking reliable Raman capabilities for routine material identification, educational instruction, or incoming quality inspection, the MR-532A provides an excellent balance of performance and value. Explore the broader micro Raman spectrometer brand comparison to understand how the MR-532A compares against international alternatives.
