Examples of Nanofinder 30A Raman Micro spectroscopy systems with extended functionality

Nanofinder 30A configuration for bio researchers

For bio applications the Nanofinder 30A system can be equipped with an inverted Microscope and a Galvano mirror scanner (to keep the sample in resting state and move the laser beam for confocal imaging).

Nanofinder 30A extension for CARS Microscope

Strong Raman signals generated in the non-linear CARS (Coherent Anti-Stokes Raman Scattering) effect can be obtained in very short acquisition time and, hence, fast mapping can be realized. Ultrashort laser pulses are required for generating CARS signals from the sample. Since the wavelength of CARS signals is shorter than the excitation laser wavelength there is no influence from sample fluorescence background. Sample preparation, such as fluorescent labeling, is not required for obtaining fast 3D CARS images

Fluorescence Lifetime Imaging Microscopy (FLIM) extension

Fluorescence lifetime measurement can be realized by combining Nanofinder 30A with ultrashort pulsed lasers such as Ti:sapphire laser or a picosecond semiconductor laser with a time correlated single photon counter (TCSPC) or a streak camera detector. Fluorescence intensity and lifetime images are obtained in 3D with high spatial resolution and high sensitivity. Observations of intracellular molecules dynamics in biology or carrier dynamics in semiconductor materials are examples of possible applications. Temperature control with heating/cooling chamber or cryostat is also available. Sample imaging can be realized by moving the laser beam with a Galvano mirror scanner.
