The Zeiss LSM 980 NLO Airyscan 2 confocal/two-photon laser-scanning microscope is an inverted laser-scanning system that features the Airyscan 2 super-resolution detector which enables up to 90-nm resolution with Airyscan Joint Deconvolution and includes the SR-4Y and SR-8Y multiplex modes for fast parallel imaging at frame rates of up to 47 fps, a 34-channel spectral array consisting of a 32-channel GaAsP PMT spectral detector and two multi-alkali PMTs, two internal GaAsP PMT detectors in the BiG.2 module for confocal, FCS, and photon-counting experiments, two external non-descanned GaAsP PMT detectors for two-photon microscopy, temperature and CO2 control, six visible laser lines for single-photon excitation, and the tunable Spectra-Physics Mai Tai eHP DeepSee Ti:sapphire laser for two-photon excitation.

Middle: The same specimen after Airyscan processing, which enables up to 120-nm resolution in full super-resolution mode (1.25-AU equivalent). Right: Resolution test using GATTA-SIM 90B nanorulers specimen after Airyscan Joint Deconvolution, which enables up to 90-nm resolution.
