The latest addition to the high-throughput automated microscope line, the CellDiscoverer 7 LSM900 Airyscan2 is installed in L3 confined space for imaging infected live cells by full field fluorescence microscopy or confocal imaging.
The Celldiscoverer 7 is a fully integrated, high-end automated live cell imaging system. Tailor the system to your applications with various incubation and detection options. A hardware focuser automatically detects and maintains focus after detecting the thickness and optical properties of the sample holder for demanding long-term imaging. Autocorr objectives correct for spherical aberrations to provide sharp contrast and high resolution. The automated microscope offers a range of built-in incubation options to create the right environment for your live cells.
A multimodal approach:
– Acquisition automation
– High sensitivity confocal imaging with GaAsP detectors and Airyscan 2
– Fast imaging thanks to the multiplex mode
– Increased resolution thanks to the AiryScan 2
– Combined mode for full-field and confocal acquisitions
Objectives (adaptive optics) :

BF illumination: brightfield contrast, oblique contrast, adaptive phase contrast (PGC)
Fluorescence: Fluorescence illumination unit composed of 4 LEDs divided into 2 Colibri units
Confocal Imaging LSM900 with 405, 488, 561 and 640 nm diode laser bench
1- WF mode acquisition. It uses the camera mode and allows a fast scan. It can be used as final imaging or as a fast prescan.
2- WF acquisition + GPU deconvolution (24GB): used for fast optical sectioning type acquisitions on very large fields.
3- Confocal LSM 900 acquisition. It has all the characteristics of a traditional confocal (including FRAP etc). It is mainly used for punctual applications on areas of interest determined after a camera prescan (Mode 1).
4 – Airyscan Confocal Multiplex 2 acquisition: This allows to have not only a scan speed multiplied by 2 but also a gain in sensitivity. This modality is applied either on large fields, or on regions of interest
5- Airyscan Super Resolution Multiplex 2 acquisition: this allows an increase in resolution by a factor of 1.5x and a scanning speed in SR mode multiplied by a factor of 2. This modality focuses on regions of interest
The confocal modalities can be combined with a WF acquisition to target only the color of interest in confocal or SR mode.
