The system is set up for FRET, FRAP and FLIM analysis. The second system is a Zeiss LSM 700 (upright) equipped with 4 solid state lasers (405 nm, 488 nm, 555 nm, and 635 nm). The scan head has 2 confocal PMTs, a variable secondary dichroic beamsplitter and a transmitted light detector. The third system is a Zeiss LSM 880, inverted) equipped with spectral array detector (GaAsP), 2 single-channel PMT detectors, 32-element image scanning (Airy) detector (GaAsP), motorized piezo stage, hardware autofocus, stage incubator and 5 lasers (405 nm, multi-line Argon [458/488/514 nm], 561 nm green diode, 594 nm HeNe and 633 nm HeNe. The system is capable of high-resolution (image scanning), FCS and fast live-cell imaging.

3) Multi-photon laser scanning microscopy, supported by a Zeiss LSM 510 META NLO (fixed stage upright) equipped with a Spectra-Physics Broadband (710-990 nm) MaiTai Ti:sapphire laser and 3 visible lasers (multi-line Argon, 561 DPSS, HeNe 633), 2 non-descanned detectors, 3 descanned detectors (including a META detector for spectral scanning) a transmitted light detector, and a variety of objective lenses (dry, oil, multi-immersion, water immersion). A Luigs & Neumann 380 FM workstation (with slice chamber & in vivo bridges) and physiology equipment (stimulators, VP timing unit, A/D converters, multiclamp amplifier, line heaters, peristaltic pump, pipette puller) are linked with the system to facilitate simultaneous imaging & physiological recording;
