| - | The Zeiss LSM 7 Live //confocal line-scanning microscope// is a fast imaging system able to analyze high-speed processes with a time resolution of just a few microseconds. It is an upright microscope equipped with water dipping objectives specially suited for live samples in aqueous media. The scanning unit uses a laser beam with a rectangular cross-section to [[http://www.nature.com/nmeth/journal/v3/n11/thumbs/nmeth971-F2.jpg|illuminate a whole line in the sample]], instead of a single point. This makes image acquisition by its array CCD detectors faster than conventional PMT light detection but it also lowers the Z-resolution due to the usage of slits instead of conventional pinholes. Note that the system is equipped with two lasers (488 and 561 nm) but dual color imaging is not advised since there are no bandpass filters in the system (channel crosstalk is likely to occur). A UV laser controlled by galvanometric mirrors is available for precise ablation in user-defined regions of interest. The spatial resolution of this system is not as high as a //point-scanning confocal system// such as the [[zeiss_lsm_880|Zeiss LSM 880]] or [[zeiss_lsm_710|Zeiss LSM 710]] but it is much faster than these two systems, achieving scanning speeds which may be even higher than the [[3i_marianas_sdc|3i Marianas SDC]] spinning disk if the acquisition is performed only in a few lines. If your personal computer cannot handle all the data you collected, check out the [[big_guy|Big Guy]] or [[colossus|Colossus]]. | + | The Zeiss LSM 880 with Airyscan is a //confocal point-scanning microscope// able to generate high-resolution three-dimensional images of thick specimens with high sensitivity and low photodamage. It is an inverted microscope specially suitable for live cell imaging and photobleaching experiments, equipped with a large size incubator for temperature control and CO2 supply. Its [[http://www.zeiss.com/content/dam/Microscopy/Products/laser-scan/LSM%20880/zeiss-lsm880-airyscan-principle-672.jpg|Airyscan]] 32 channel area detector is able to collect all light from an Airy pattern simultaneously, allowing for increased resolution (140 nm laterally and 400 nm axially, at 488 nm). Its scanning unit further includes two PMT detectors (one of them cooled for single photon counting) as well as a GaAsP detector. It is equipped with lasers from violet to far red (405, 458, 488, 561 and 633 nm excitation wavelengths). With this system you can perform optical sectioning of fluorescent samples which are too thick for a widefield system such as the [[bioimaging:zeiss_axiovert_200m|Zeiss Axiovert 200M]]. Image resolution and detection sensitivity are higher than faster confocal systems such as a spinning disk or the [[bioimaging:zeiss_7_live|Zeiss LSM 7 Live]], but image acquisition is slower. If you need to use a 594 nm laser or a 40x water objective for higher working distances, check the [[bioimaging:zeiss_lsm510_meta|Zeiss LSM 510 META]] confocal point-scanning system. If your personal computer cannot handle all the data you collected, check out the [[bioimaging:bigguy|Big Guy]]. |
