Light Sheet Microscopy
In Light Sheet fluorescence microscopy the samples are illuminated from the side by a thin sheet of light positioned exactly at the focal plane of the imaging objective. Illumination light is confined only to a thin section that is being imaged, avoiding the unncessary and potentially photo-toxic illumination of other areas of the sample. Use of high-end (82% Peak Quantum Efficiency) sCMOS cameras allow for sensitive detection and resolution. This approach considerably reduces the out-of-focus fluorescence compared to wide-field epi-fluorescence, therefore improving contrast, and reducing photobleaching. The method is fast as it does not rely on raster-scanning a laser beam and is readily compatible with large field of views.
