Andor Dragonfly - Confocal / TIRF / Super Resolution
The Dragonfly microscope is a fully automated multimodal microscope that can be used for confocal, total internal reflection microscopy (TIRF) and super-resolution (localization-based techniques such as: PALM, dSTORM, PAINT, etc.).
Applications:
- Spinning disk confocal imaging. In contrast to point scanning confocals, such as the LSM880 and CD7 that serially acquire one focal point at a time to reconstitute a 2D image, the Dragonfly acquires confocal images by simultaneously acquiring thousands of spots from the focal plane. This setup enables the Dragonfly to provide several important advantages over point-scanning confocals:
- Faster speed (up to ~200 frames per second), which is ideal for fast 2D or 3D time-series or tile scanning.
- Gentler imaging – photobleaching and phototoxicity are greatly reduced, which is better for live cell imaging.
- The high sensitivity of cameras is well suited for dim specimens.
- Super-resolution imaging. The Dragonfly can perform 3D localization- based microscopy techniques (dSTORM, PAINT, etc.) that improve spatial resolution to ~30nm laterally, and ~50nm axially.
- TIRF microscopy. a technique allowing the confined excitation of fluorophores within ~100nm above the coverslip.
Objectives: 10x/0.45, 20x/0.8, 40x/1.1 W, 40x/1.3 Oil, 63x/1.47 Oil.

Zeiss Celldiscoverer7
The Celldiscoverer 7 is an automated boxed microscope with a user-friendly interface that allows wide-field, confocal (LSM 900), and super-resolution imaging by means of its Airyscan2 detector. The system is an inverted microscope capable of live cell imaging experiments with a variety of incubation conditions. It has enhanced automated functionality such as Autocorr objectives, which enable the system to automatically detect a variety of sample holders and adjust for spherical aberrations. The CD7 is also equipped with an autoimmersion system that automatically applies water to its water immersion lenses and maintains the volume of immersion water to permit live cell imaging over a long duration. The system uses LED illumination, which has low phototoxicity and long-term stability.

- Multiphoton excitation microscopy. It can be used to image up to 10x deeper than confocal microscopy.
- Super-resolution imaging. The Airyscan can provide a 2-fold increase in resolution compared to conventional confocal microscopy.
- High-speed imaging. The Airyscan detector can be used to image 4 times faster than the confocal mode (up to 20fps at 512*512). The 880 is also equipped with a piezo-electric stage for high-speed acquisition of z-stacks.
- Confocal reflection microscopy. It can be used to image collagen fibers and surface microtopography.
- FRET, FRAP, FLIP.
- Fluorescence Correlation Spectroscopy imaging. It provides quantitative data on concentrations, diffusion coefficients, molecular transport and interactions.
