System Enables High-res Imaging, Spectroscopy

WITec’s fully automated, easy-to-use Raman imaging system, apyron, features enhanced spectral resolution in 3-D confocal Raman imaging, and extremely sensitive laser power determination with a mouse click.

The automated Raman microscope system includes laser wavelength selection with subsequent adjustment of all associated spectrometer and microscope components to ensure optimized system performance. The absolute laser power determination and regulation in 0.1 milliwatt steps preserves delicate samples and guarantees the reproducibility of measurement conditions. Spectral resolution is excellent, down to 0.1 rel 1/cm per pixel ( at 633 nm excitation). Highly detailed spectral information is given for every image pixel, and more than 16 mio. Raman spectra can be acquired in a single dataset. The system setup includes TrueSignal to maximize the light into the fiber output of the microscope. Thus, the automated Raman system delivers images with enhanced spectral and spatial resolution in 3-D, limited laterally only by physical law. The UHTS 600, a new 600-mm focal length spectrometer designed specifically for automated Raman imaging, enables challenging experiments at even very low light intensities. Versions are available for a wide variety of excitation wavelengths and optimized for their specific lasers.
