Witec has introduced a multi-wavelength excitation-laser coupling unit for the Alpha300 and Alpha500 microscope series.
The company said it is now possible to switch between up to three laser sources by rotating 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-optimised filter set, enabling high throughput and contributing to the 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 more versatile and applicable to a range of applications.
