Leica STED & FLIM
Light MicroscopyConfocal and superresolution microscopy
With the Leica SP8 and its choosable modules STED and FLIM you can nearly address any scientific challange which can be answeered by light microscopy. With our Leica SP8 you can perform normal light and fluorescence microscopy. The incubation chamber with a CO2 module easily allows live cell imaging using a resonant scanner equipped device. In case you want to investigate life time of fluorescence stimulated molecules you are welcome to use the FLIM module. In case you want to investigate your samples in more detail you can apply our 595 nm depletion laser in the STED module which under best conditions allows to gain a lateral resolution as tiny as 50 nms.
