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, high speed and low photodamage. It is an inverted microscope especially suitable for live cell imaging and photobleaching experiments, equipped with a large size incubator for temperature control and CO2 supply and with Definite Focus for hardware focus control during long time-lapse acquisitions. The stage is motorized and furthermore equipped with a piezo for Z displacement so fast 4D imaging is possible in multiple stage positions. Its 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). It can also be used in Fast Mode, which enables parallel excitation and detection of four image pixels. The result is a speed improvement by a factor of four, while maintaining the sensitivity of Airyscan and 1.5x resolution improvement. Its scanning unit further includes two PMT detectors (one of them cooled) as well as a GaAsP detector for increased sensitivity (45% QE compared to ~25% QE for conventional PMT). It is equipped with lasers from violet to far red (405, 458, 488, 514, 561, 594 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 Zeiss Cell Observer or the Zeiss Axiovert 200M. Image resolution with Airyscan is higher than the Zeiss LSM 710 and detection sensitivity is also higher than the spinning disks 3i Marianas SDC and Zeiss Cell Observer SD. If your personal computer cannot handle all the data you collected, check out the Big Guy or Colossus.
