SPIM microscope

Light sheet fluorescence microscopy or LSFM splits fluorescence excitation and detection into two separate light paths, with the axis of illumination perpendicular to the detection axis. That means you illuminate a single thin section of your sample at one time, generating an inherent optical section by exciting only fluorescence from the in-focus plane. No pinhole or image processing is required for light sheet microscopy. Light from the in-focus plane is collected on the pixels of a camera, rather than pixel by pixel as, for example, in confocal or other laser scanning microscopy approaches. Parallelization of the image collection on a camera-based detector lets you collect images faster and with less excitation light than you would with many other microscope techniques.
