-{{  :​confocal_vs_2photon.png?​0x300}} The Leica SP8 MP is a both a confocal and //​multi-photon microscope//​ able to generate high-resolution three-dimensional images of thick specimens. Multi-photon excitation (most commonly two photon excitation) is particularly advantageous for imaging thicker samples. Rather than exciting the fluorophore with one photon, multi-photon excitation is produced by two or more lower energy photons which can penetrate deeper in the sample. Moreover, contrarily to confocal, the multi-photon excitation light will only achieve sufficient intensity to cause fluorescence in a specific region. Because of this, no pinhole is needed in multi-photon microscopy to exclude the light from out-of-focus planes and achieve optical sectioning. The Leica SP8 MP is an upright microscope equipped with water and glycerol immersion objectives especially suitable for intra-vital and thick samples immersed in water or glycerol imaging. In confocal mode, its scanning unit includes a spectral detector PMT to be used with a 488 nm laser for excitation. In multi-photon mode, its Insight DS+ Dual pulsed laser can be tuned from 680 to 1300 nm and has a second laser line emitting at 1041 nm, to be used with four non-descanned detectors with specific filtersets: two PMTS and two HyD detectors (hybrid detectors with 45% QE compared to ~25% QE for conventional PMT). With this system you can perform optical sectioning high resolution imaging of fluorescent samples that are two thick for confocal microscopes such as the [[zeiss_lsm_880|Zeiss LSM 880]] or the [[zeiss_lsm_710|Zeiss LSM 710]], albeit with a slightly lower resolution. If you do not need optical sectioning and your sample is thin, check out a widefield system instead, such as the [[zeiss_cell_observer|Cell Observer]] or the [[nikon_eclipse_ti|Nikon Eclipse Ti]]. If your personal computer cannot handle all the data you collected, check out the [[big_guy|Big Guy]] or [[colossus|Colossus]].+{{  :​confocal_vs_2photon.png?​0x300}} The Leica SP8 MP is a both a confocal and //​multi-photon microscope//​ able to generate high-resolution three-dimensional images of thick specimens.
