The Zeiss LSM 900 with Airyscan 2 is a point scanning confocal 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 dark large cage incubator and a stage top incubator for temperature control and CO2 supply and with Definite Focus.3 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, using the Tiles Advanced Setup of ZEN blue. Its Airyscan 2 with 32 concentrically arranged GaAsP detection elements is able to collect all light from an Airy pattern simultaneously, allowing for increased resolution (120 nm laterally and 350 nm axially in SR mode, at 488 nm). It can also be used in Multiplex Mode, which enables parallel excitation and detection in 4Y modes. The result is a speed improvement by a factor of 4x, while maintaining the sensitivity of Airyscan. Its scanning unit further includes two PMT detectors 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, 488, 561 and 639 nm excitation wavelengths). The LSM Plus deconvolution mode enhances signal-to-noise ratio by acting as a denoising step post image acquisition, allowing for high acquisition speed and low laser power. With Airyscan Joint Deconvolution (jDCV) the resolution can be improved to 90 nm (XY) and 270 nm (Z).
