Confocal Laser Scanning Microscopy

Laser scanning confocal microscopy is am optical technique that provides the opportunity for three-dimensional, high-resolution, non-destructive imaging of a whole range of samples ranging from biological cells to semiconductor devices. Our laboratories are equipped with several commercial and self-built setups tailored for different applications. In addition to the conventional LSCM we are developing also more advanced method such as two photon laser scanning microscopy, second harmonic generation microscopy, fluorescence life time imaging, etc. Some recent examples are shown below:
