Dragonfly High Speed Confocal Microscope Systems​

Dragonfly delivers outstanding multi-dimensional images from subcellular (nm) to whole organism (cm), while significantly boosting productivity.

Its unrivalled combination of speed and sensitivity allows researchers to discover unforeseen dynamic events and image live organisms for days. The new B-TIRF and super resolution modules reveal smaller details, such as the dynamics of viral infection and the ultrastructure of chromatin or organelles.

The Game-Changer in Confocal Microscopy...

Dragonfly 600 spinning disk confocal delivers leading performance for both industrial and academic users. It integrates super-resolution solutions compatible with confocal, widefield or TIRF. Furthermore, it incorporates the newly developed High Power Laser Engine (HLE) and new TIRF imaging modality, which exploits Borealis® illumination, B-TIRF (Borealis TIRF) for easy setup, more even illumination and thus more usable data across the field of view.

Use the hotspots below to explore the key features and benefits of Dragonfly 600.


Dragonfly Confocal Microscopy Applications


Whether imaging glial cells, axonal transport, large tissue sections, expanded samples (Expansion Microscopy), or super-resolved dendritic spines (SMLM), Dragonfly is the instrument of choice.

  • Combine deep imaging and high-speed scanning and get more insights faster than ever before
  • Image sensitive samples gently and for long periods of time
  • Image fast events such as calcium signalling

Cell Biology

The high sensitivity, low phototoxicity/ photobleaching and speed are ideal features for live cell imaging applications such as microtubule dynamics or intracellular organelle trafficking

With B-TIRF researchers can address live events at the edge of the coverslip, such as vesicle fusion or membrane receptor trafficking. B-TIRF delivers increased signal to noise in SMLM applications

The HLE can be used in combination with any imaging modality (confocal, widefield and B-TIRF) for SMLM applications, such as ultrastructural organisation of organelles, chromatin and epigenetic organisation, mitochondrial membrane structure.

Cancer Research

Dragonfly allows researchers to study cancer cell behaviour interaction with the environment and spatial distribution of the tumor both in fixed and live cells.

  • Gentle imaging: view live images of cancer tissues for hours or days
  • High-speed acquisition and optimized pinhole spacing: image fast and deep into thick tissues or organoids
Request Pricing

Developmental Biology

Dragonfly's optimized pinhole size allows imaging very deep into thick organisms - up to the millimetre range.

  • Borealis™ uniform illumination and stitching: visualise the complete organism as if it were a single snapshot
  • Cross-scale imaging: a single stitched snapshot contains all information from both high and low magnification simultaneously
  • Exceptional sensitivity and speed: image delicate processes for hours or days
  • Multipoint technology: image high-speed events in confocality, such as blood flow or cilia beating during development

Transcriptomics and Proteomics

Omics research is used for multiple applications, such as predicting disease progression based on gene expression mappings, assessing tumor microenvironments and cancer severity, etc.

Omics-related sciences gather information about Xn biological molecules to characterize and quantify entire pools of molecules.

Dragonfly's highly sensitive detectors, exceptionally high background rejection, acquisition speed and Uniform illumination make it the perfect system for Omics applications

Microbiology and Virology

The resolution and sensitivity delivered by Dragonfly 600 makes it a unique system for studying micro-organisms:

  • Gentle illumination allows imaging growing yeast or fungus culture for very long times
  • B-TIRF modality allows live insights into virus-host infections
  • Exploit super-resolution capabilities to study the microworld of fungus, yeast and bacteria and extend knowledge about the biology of infection and host-pathogen interactions

Borealis Total Internal Reflection Fluorescence (B-TIRF) is Andor’s proprietary TIRF module available on Dragonfly 600.

  • TIRF imaging with reduced Aberration
  • Supports both 60x and 100x TIRF objective lenses
  • High-quality results with a simple set up
  • Image dynamic events at the edge of the coverslip (e.g. membrane fusion events, receptor signaling, and infection dynamics)
  • Ideal to increase the signal-to-noise ratio in single-molecule imaging
Request Pricing
Comparing conventional TIRF and Borealis TIRF: Left image: single mode TIRF is sensitive to optical contamination resulting in interference fringes and uneven illumination. Right image: the same specimen imaged in B-TIRF with contamination, results in high quality images which reflect the true distribution of fluorescence in the specimen.

Super-Resolution: Localization Microscopy

With Dragonfly you can select from a number of super-resolution approaches all from the same imaging system. ​

  • The HLE (High Power Laser) delivers high-power densities for single-molecule localization microscopy (SMLM) applications such as dSTORM and DNA-PAINT
  • Localization precisions up to 2 nm with a corresponding resolution up to 20 nm 
  • The 3D super resolution optics delivers axial information over 1 um range​ in a single image
  • 3D SMLM is compatible with all imaging modalities (Widefield, B-TIRF and confocal) ​

Super-Resolution: SRRF Stream+

SRRF (Super-Resolution Radial Fluctuations) offers a highly effective software-based approach to super-resolution imaging. Our exclusive development, SRRF-Stream+, accelerates processing by delivering real-time super-resolution.​

  • Ideal for live cell imaging
  • Compatible with normal fluorescent labels​

Widefield Fluorescence

Laser-illuminated widefield fluorescence is ideal for studies that do not benefit from confocal imaging. Dragonfly users can easily change to widefield mode, with no need to switch microscope ports. ​

  • Image yeast, bacteria and very thin samples​
  • Image light-sensitive samples while minimizing the illumination power and maximizing photon collection ​
  • Collect all the photons when every photon counts e.g. single molecule imaging
  • Combine with SRRF-Stream+ or Clear View GPU-powered deconvolution to increase signal to noise and resolution

Transmitted Light Microscopy

All imaging modalities can be combined with transmitted light techniques (DIC or phase contrast) to expand your imaging capabilities even further. DIC or Phase Contrast can be used in a variety of ways including:​

  • Label free imaging of biological samples​
  • An extra reference channel as part of your regular fluorescence imaging protocols

Dragonfly is fast, sensitive, and fantastically flexible. We have 120 research groups working at our Core Facility every year, and they bring in everything you could imagine to image. Having the flexibility to switch between different modes and colors, and having a system that is very sensitive for single-molecule imaging through to spinning-disk confocal microscopy, is amazing for us.
