  • RayShield Coupler
Jul 2013
WITec GmbHRequest Info
ULM, Germany, July 3, 2013 — The RayShield Coupler by WITec is now available for the alpha300 and alpha500 microscope series, allowing the acquisition of Raman spectra and wave numbers down to less than 10 rel. cm−1.

The high-transmission system includes a narrowband filter set that is optimally aligned to detect Raman lines extremely close to the Rayleigh line while maintaining suitable Rayleigh shielding, enabling additional spectral information from Stokes and anti-Stokes Raman signals to be obtained.

The RayShield Coupler is available for a variety of laser wavelengths from 488 to 785 nm.

Applications include semiconductor research, the pharmaceutical industry, the life sciences, nanocarbon research and materials science.

Raman spectroscopy
That branch of spectroscopy concerned with Raman spectra and used to provide a means of studying pure rotational, pure vibrational and rotation-vibration energy changes in the ground level of molecules. Raman spectroscopy is dependent on the collision of incident light quanta with the molecule, inducing the molecule to undergo the change.
