The key to Nanophoton's advanced technology employs is a line-shaped laser illumination combined with a two-dimensional CCD sensor to simultaneously capture 400 spectral data points in a single exposure. By utilizing galvanometer-based laser scanning, the RAMANtouch delivers high-speed, high-precision Raman imaging, efficiently mapping hundreds of thousands of pixels within minutes—all without relying on an EMCCD.

Laser Scanning via Galvanometers:
The RAMANtouch utilizes a galvanometric mirror for laser beam scanning, allowing the laser to move freely under the objective lens without shifting the sample stage. This method offers superior precision and speed compared to traditional table scanning. The perpendicular incidence of the laser beam across the observation plane enables specialized measurement modes:
- Laser Line Scanning
Scans the sample surface with high spectral and spatial resolution efficiently
- Point Scanning
Generates quick overview images by targeting areas with distinct Raman spectra.
- AreaFlash Measurement
"Flashes" the Raman laser line across the field of view to create an average spectrum of the entire area, facilitating ultra-fast measurements of large regions.

Exceptional 3D Raman Imaging Capabilities
The confocal optics of the RAMANtouch allow non-destructive analysis within samples. Using line illumination and a high-precision stage, it rapidly produces 3D Raman images of transparent samples, offering insights into internal structures and component distribution. For example, it can detect inside transparent fibers, such as bi-component PE (cladding) and PET (core) fibers, with acquisition times between 20 to 30 minutes.
