LSM 900 & Airyscan2

The Zeiss LSM900 is a compact system delivering superb performance for routine fixed sample imaging using a laser scanning confocal. Mounted on an inverted microscope, it enables the scan live cells by using water immersion lenses, a stage-top chamber for environmental control and focus drift correction.

The system incorporates a smart, efficient detector disposition based on two variable beam splitters that drive the light to 3 detectors: 2 standard GaAsPs with high sensitivity across the spectrum, and the Airyscan2 detector. This is an array of 32 single GaAsP detectors arranged as a rosette which, in combination with the 40x / 1.3 objective, allows for super-resolution performance (down to 150 nm). Alternatively, this optical combination allows for use as a slit scanning confocal, increasing scanning speed by 8x.

Additionally, the system boasts an AxioCam 702 mono camera, enabling widefield acquisitions using the Colibri7 LED light source.
