===== Microscope overview =====

{{  :lightsheet_z.jpg?0x380|}} The Zeiss Lightsheet Z.1 is a //light sheet fluorescence microscope// able to image optical sections of large samples at subcellular resolution and very fast rates, with almost no phototoxicity or bleaching. [[https://www.zeiss.com/content/dam/Microscopy/Products/imaging-systems/lattice-lightsheet/lattice-lightsheet-7/zeiss-lattice-lightsheet-7-beam-splitting.svg|It splits fluorescence excitation and detection into two separate light paths]], with the axis of illumination being perpendicular to the detection axis. 
[[https://imm.medicina.ulisboa.pt/facility/bioimaging/lib/exe/fetch.php?media=lightsheet_illumination.jpg|Since only a single thin section of the sample is illuminated by the light sheet]], optical sectioning is achieved without a pinhole or image processing deconvolution. Light from the in-focus plane is collected by a sCMOS camera rather than pixel by pixel as in a point scanning laser confocal. This allows you to collect images faster and with less excitation light than you would with many other optical-sectioning microscopy techniques. You can image living samples in water or fixed samples where [[https://imm.medicina.ulisboa.pt/facility/bioimaging/lib/exe/fetch.php?media=en_poster_overview-clearing-methods_rel-2.0.pdf|tissue clearing]] has been performed. Samples are mounted not on coverslips but inside [[https://imm.medicina.ulisboa.pt/facility/bioimaging/lib/exe/fetch.php?media=lightsheet_chambers.jpg|special chambers]] that provide heating and cooling. The system is equipped with lasers from green to far red (488, 561 and 638 nm excitation wavelenghts) and appropriate fluorescence emission filters. With this system you can image live drosophila and zebrafish samples or use tissue clearing to perform optical sectioning deep into large fluorescent samples such as tissue sections, brains, embryos, organs, spheroids or biopsies. If you need higher resolution and have a smaller and thinner sample, check instead a confocal microscope such as the spinning disks [[3i_marianas_sdc|3i Marianas SDC]] and [[zeiss_cell_observer_sd|Zeiss Cell Observer SD]] or the point scanners [[zeiss_lsm_880|Zeiss LSM 880]] and [[zeiss_lsm_710|Zeiss LSM 710]]. A dedicated computer running [[https://www.arivis.com/en/imaging-science/arivis-vision4d|arivis Vision4D]] is available for working with multi-channel 2D, 3D and 4D images you generate in the system.
