Excitation Wavelength Selection with a Flick of the Thumb
21 Jun 2011

New WITec Multi-wavelength Coupling Unit for the alpha300 and alpha500 series. With the most recent introduction of a new multi-wavelength excitation-laser coupling unit WITec has further advanced the ease-of-use of its microscope series.

It is now possible to switch between up to three laser sources by the simple rotation of a filter wheel. Calibration and alignment of the laser beam path is guaranteed at all positions assuring accurate and variable Raman Imaging. Each excitation wavelength features a high-quality and wavelength optimized filter set, enabling the highest throughput and greatly contributes to the exceptional speed and sensitivity of WITec’s systems.

Experiments specifically requiring a variety of lasers, for example, to eliminate fluorescence can benefit from such a multi-laser setup, making the alpha300 and alpha500 series even more versatile and applicable to a wide range of applications.
