Raman revolution

In the field of modern microscopy, few techniques hold as much promise and potential as Raman microscopy. Combining traditional microscopy and Raman spectroscopy, this method offers researchers and industry professionals a powerful tool to chemically analyze materials at a microscopic scale.

To truly understand the significance of Raman microscopy, it’s essential to explore its historical roots. Named after Indian physicist Sir C.V. Raman, who discovered the Raman effect in 1928, this technique relies on light scattering off a sample.

Raman scattering, also known as the Raman effect, occurs when photons interact with matter. This results in both a transfer of energy and a change in the direction of light. Typically, this effect involves molecules gaining vibrational energy from incident photons emitted by a visible laser. This causes the photons to shift to lower energy levels. Raman scattering provides detailed insights into the chemical composition and structure of materials under study.

Raman applications

From its beginnings in academic laboratories, Raman microscopy has become essential in scientific research and industrial applications. In materials science, it characterizes substances like polymers, ceramics, and pharmaceuticals. Thus aiding in the development of novel materials with tailored properties.

In the pharmaceutical industry, Raman microscopy plays a crucial role in drug development and quality control. It identifies active pharmaceutical ingredients (APIs), detects impurities, and monitors crystal forms, ensuring product safety and consistency. Additionally, it enables researchers to study drug-cell interactions and distribution within cells.

Raman microscopy is also valuable in forensics, environmental science, and geosciences. Its non-destructive nature and ability to analyze samples in situ make it useful for various investigations and studies.

RamanTouch and RamanWalk – Groundbreaking

RAMANtouch and RAMANwalk introduce groundbreaking Raman imaging technology, revolutionizing speed, precision, and automation.

Departing from traditional methods, they utilize line-shaped laser illumination and a two-dimensional CCD to capture an impressive 400 spectra in one exposure. This enables rapid and precise Raman imaging of hundreds of thousands of pixels within minutes. And all that without the need for Electron-multiplied CCDs (EMCCDs).

Central to their operation is Laser Scanning via Galvanometers. By allowing the laser beam to freely scan the point under the objective lens without moving the sample stage unmatched precision and speed is ensured. This enables special measurement modes like Laser Line Scanning, Point Scanning, and AreaFlash measurement, each offering unique advantages in accuracy and versatility.
