Dual-Laser Raman Spectrometers: Revolutionizing the Industry with RexerLab's MRID


RexerLab, a leading provider of Raman spectrometers in the USA, Germany, Switzerland, and Austria, proudly introduces the MRID, a cutting-edge dual-laser Raman spectrometer. This innovative system, patented by our manufacturer ProTrusTech, has a wide range of applications and offers several benefits over traditional single-laser systems. In this article, we will delve into the unique features of the MRID and explore some examples of its applications in various fields.

The MRID is designed with a built-in free space dual-laser system that does not require an optical table. This high-stable optical system allows for seamless switching between different laser wavelengths and simultaneous display of their respective spectra on screen. This user-friendly feature is particularly advantageous for users without an optical background. The MRID also boasts a robust microscopy system platform and state-of-the-art software that enhances its overall functionality.

Key Features of the MRID

  1. Dual-laser excitation light sources: The MRID includes a 532 nm laser excitation light source with a TEM00 mode and a 785 nm laser excitation light source with a Near TEM00 Mode. These lasers can be fine-tuned by the software and offer optimal spot sizes under 100x objective lenses.

  2. Polarization capabilities: The MRID contains a 532nm polarizer module, enabling researchers to measure the polarization Raman difference in samples with high crystallinity or thin films. The software also automates the polarizer angle control, signal angle optimization, and continuous angle measurement.

  3. Laser energy control: The MRID offers two laser energy control methods, both controlled by the software: (1) laser output adjustment by 1 mW/step, and (2) continuous N.D filter with an attenuation rate accuracy of at least 1% and a range of 1~100%.

  4. Impressive range and resolution: The MRID's dual-laser system boasts a wide range and high resolution for each laser excitation light source, ensuring accurate measurements and detailed analysis.

  5. Advanced microscopy system platform: The MRID is compatible with high-quality microscope stands, such as the Olympus BX-43, and includes a high-resolution color camera CCD lens for observing and storing white light images.

  6. Versatility: The MRID can be combined with nanomaterials for Surface-Enhanced Raman Scattering (SERS) and scanning tunneling microscopy (STM) to expand Tip-Enhanced Raman Scattering (TERS).

  7. Comprehensive software: The MRID features integrated software like RAMSpec, OPUS, or WiRE TM, which offer a wide range of functions, including scanning and image switching, laser energy adjustment, one-click laser wavelength switching, and polarization automatic search for the best angle signal.

Applications of the MRID

The MRID's dual-laser system makes it suitable for various applications, including:

  1. Material science: The MRID can be used to analyze the crystal structure and chemical composition of materials, as well as the stress distribution in thin films and semiconductors.

  2. Pharmaceutical research: The MRID can help identify active pharmaceutical ingredients and impurities, monitor polymorphic changes, and study drug delivery systems.

  3. Forensic science: The MRID can be utilized to analyze trace evidence, such as fibers, paint chips, and inks, providing crucial information in criminal investigations.

  4. Nanotechnology: The MRID's compatibility with nanomaterials allows researchers to study Surface-Enhanced Raman Scattering (SERS) and Tip-Enhanced Raman Scattering (TERS), enabling the investigation of molecular structures and chemical compositions at the nanoscale, with potential applications in areas such as nanoelectronics, energy storage, and drug delivery systems.

  5. Art and cultural heritage preservation: The MRID can be used to study the chemical composition and degradation of pigments, binders, and other materials used in artworks and historical artifacts, aiding in their conservation and restoration.

  6. Environmental science: The MRID's capabilities make it ideal for monitoring air and water pollution, detecting contaminants, and analyzing the molecular structure of pollutants to understand their environmental impact and devise effective remediation strategies.
