Confocal Microscopy
Commercial
Leica: Leica-SP8 (Archived Product Replaced by STELLARIS 5 & STELLARIS 8)
Carl Zeiss: LSM 880, with Airyscan: The Zeiss LSM880 with Ariyscan 2 is an inverted confocal microscope. The system is equipped with 7 laser lines 405nm, 458nm, 488nm, 514 nm, 561nm, 594nm and 633 nm. The newly designed excitation beam is elongated in y which acquires four lines of image information instead of only one with just one horizontal scanner movement.

In this talk, two-photon microscopy-which uses strong pulsed infrared lasers to produce detailed images inside biological samples-is introduced. It can be utilized to image inside of living animals as well as thick tissue specimens.

The innovative method of light sheet microscopy, also known as selective plane illumination, is discussed in this talk (SPIM). This allows for long-term 3D imaging of dense specimens like growing embryos with less photobleaching and phototoxicity because it uses two objectives-one to illuminate the sample and the other to image it.
Super-resolution microscopy
In comparison to traditional microscopy with diffraction-limited optics, a range of contemporary techniques are surveyed in this presentation. These include various patterns of illumination (such as STED and SIM microscopy) or methods that construct images by randomly turning on single fluorescent molecules and precisely localizing each molecule in space (STORM, PALM, FPALM).
During 20 years of friendship, Betzig and Hess collaborated to create the first super-high-resolution PALM microscope after working independently and jointly in academia and industry. They describe the journey to us, emphasizing how their diverse and unusual backgrounds gave them the necessary abilities to complete the project.
