The Zeiss Elyra Superresolution Microscope is a developmental superresolution microscope with capabilities to push imaging past the classic diffraction limit. Typically visible light microscopes cannot achieve spatial resolution of greater than 200-250 nanometers. This system has two different imaging modalities to push this limit as low as 20 nanometers.
This microscope has a unique design, allowing for a great deal of customization of the sample space and experimental design. The system is designed for up to four-color total internal fluorescence (TIRF), photoactivation (PA), fluorescence resonance energy transfer (FRET), widefield correlation spectroscopy (WCS), spatio-temporal image correlation spectroscopy (STICS), and fluorescence recovery after photobleaching (FRAP) experiments, all at high frame rates. Single-molecule measurements can be enhanced with a pair of single-photon avalanche photodiodes (APDs) and a pulse correlator for fluorescence correlation spectroscopy (FCS) and fluorescence cross-correlation spectroscopy (FCCS) experiments. An environmental chamber allows for these techniques to be extended to live cell samples.
The Microtime200, manufactured by the German-based PicoQuant GmbH, is generally used in conjunction with the TCS SP5 microscope. By using the lasers from the TCS SP5, the Microtime200 is capable of measuring how fast proteins move within the cell (diffusion) and protein to protein interactions.
This microscope combines a total internal fluorescence (TIRF) and highly inclined and laminated optical sheet (HiLo: https://www.nature.com/articles/nmeth1171) modalities in one instrument. The TIRF modality allows user to image molecules at surface of cells and apply super- resolution imaging techniques such as PALM and STORM. HiLo modality offers the possibility of exciting a thin inclined plane within cells or thin layer of cells within few micrometers of a live animal tissue. Automatized variability of angle of HiLo emergence and camera imaging allows for fast sectioning of sample. The system is also supplemented with NIDAQ board and control with external trigger, which combined with the versatile illumination sequence option makes this ideal microscope for complex experiments involving the correct timing of imaging following an external stimulus of cells or animal. Definite focus is perfectly controlled using Nikon PFS system making it ideal for long term live cell or animal imaging.

Fitted with Hybrid Dectors (HyD) for enhanced sensitivity, and interchangeable Galvano and resonant scanners, this system is suitable for applications requiring both speed and/or improved signal-to-noise. Its Gated-STED module also enables collection of super-resolution images allowing investigators to distinguish objects and structures beyond the conventional resolution limit of light.
The Leica TCS SP8 DLS (Digital LightSheet) is an inverted laser scanning microscope capable to be used for confocal imaging and light sheet imaging.

Fluorescence Lifetime Imaging (FLIM) adds another dimension to conventional intensity based imaging methods. FLIM is not affected by fluctuations in the fluorescence intensity and permits to discrimination between fluorophores with similar emission spectra (and from auto-fluorescence. It can be used to probe local environmental conditions (e.g., pH value), to determine ion concentrations, to study intracellular signal transduction or to distinguish between different tissue components.
