LS1 Live

Long-term live imaging

Controlled temperature and gas concentrations enable culturing and imaging of large 3D samples in physiological conditions.

Open-top configuration allows easy sample mounting and medium exchange even during running time lapse.

Multi-positions imaging with the possibility to enable independent imaging parameters for each imaged position.

Samples are held in sample chamber of custom shapes adaptable to the sample being imaged. 
Easy sample mounting from top and medium exchange possible during running time-lapse .
Sample can be placed in different media (e.g drugs vs control experiments).

User friendly and intuitive instrument operation design makes light sheet imaging very accessible.

Do you need to delete a position, extend a Z range or change laser intensity without stopping a running time-lapse? It’s possible!

Intelligent imaging: automatically adapt to the live image acquired by the system and adjust measurement parameters.

Detection and Illumination optics	Illumination: two Nikon 10X objectives, NA 0.3. Detection: one Nikon 25X NA 1.1 water immersion objective with switchable magnification (18x and 37X).
Illumination	External laser combiner with a maximum of six wavelengths (from 405nm to 685nm), Omicron LightHUB+. Transmitted light illumination (LED light source) to locate the sample and acquire transmitted images.
Light sheet specification	Light sheet generated by scanning of a Gaussian beam. Three switchable light-sheet with thicknesses (FWHM) of approximately 1.5, 2.2 and 3.3 μm for different sample sizes. Automatic position-specific light-sheet alignment.
Detection camera	One high sensitivity Hamamatsu ORCA-Fusion USB3 cameras. Field of view: 18X: 800µm; 37X: 400µm Pixel size: 18X 347nm; 37X 173nm
Sample part	Motorized XYZ sample stage with maximum X travel range of 50mm Multiple sample located in a open-top FEP sample chamber (multi-well).
Sample incubation	Recirculating air temperature controller from 5°C above ambient temperature to 40°C. CO2 concentration control range 4-10%. O2 concentration control range 5-15%.
