3D Structured Illumination Microscope (3D SIM). This is a fluorescence microscopy technique capable of achieving down to 100-200 nanometers resolution*. The 'trick' used for achieving the increased spatial resolution is to modify the 3d spatial excitation field profile such that only select patterned regions of the sample are excited for each image acquisition cycle. Computational analysis of a set of consecutive images with distinct spatial illumination profiles are then used to calculate a 3d image with a better spatial resolution than can be achieved by conventional optical far-field imaging. Due to the fast sensitive cameras the microscope setup is also well suited for very fast conventional (widefield) fluorescence imaging. The microscope is equipped with 4 laser lines (405nm, 488nm, 561nm and 640nm).
