3D Super-resolution spinning disk
Recent progress in fast spinning disk confocal imaging have enabled live cell 3D super-resolution. Thanks to the inherent low phototoxicity and high speed of spinning disk technology, dim or highly dynamic samples can be observed at a resolution down to 120 nm in x,y and 350 nm in Z. Moreover, photo-ablation or FRAP/PA capabilities can be added to widen even more the application range.
