Confocal Microscopy and UVC Laser

The platform is equipped with a Zeiss LSM900 confocal microscope mounted with quartz optics for the transmission of a 266nm UVC laser. This UVC laser is controlled by a RappOpto module, enabling targeted irradiation of living cells and small organoids.
It is also equipped with a CO2 incubation chamber.
External users interested in using the 266nm UVC laser are invited to contact the platform: epi2imaging@parisepigenetics.com.
