They were one of the first types of insect to appear on the planet around million years ago — even before dinosaurs. Look out for these beautiful creatures near ponds, streams and wetlands.

How fast can a dragonfly fly? Stitch faster in 3D than other solutions can handle in 2D. We offer the perfect solution for developmental models such as Zebrafish and C. The speed of Dragonfly combined with the integrated Fusion Stitcher will save days of valuable time to you can submit that paper ahead of the game! Fusion is the result of over person-years of shared imaging and development experience, making it easy to design an experiment, choose necessary devices and configure optimal data acquisition protocols.
It simplifies the control of the Dragonfly system, translating imaging modes into software states and fluorophores into channels to help you build protocols in just a few mouse clicks. Integrating deconvolution is simple, tasking the GPU with the associated calculations so that acquisition continues unaffected: a big time saver! Real-time 3D visualization, split channel view and MIP are fully configurable during acquisition to let you view the data in a mode which best suits your experiment.
Real-time rendering in Fusion allows for an on-going verification of the quality of your experiment and the status of your sample.
Having a near-instantaneous feedback on the 3D properties of the specimen is critical for evaluation of experimental parameters including signal to noise, illumination power and sample viability, its position in 3D and in relation to its cellular or tissue neighbours. Render quality and speed can be rapidly adjusted following any change in your experiment and can be easily accessed in the Fusion software control panel.
Protocol manager puts you in control of all the tools necessary to create acquisition sequences. It will guide you through the necessary steps of your imaging experiment to produce the most insightful and data-laden image stack. Add channels from the desired imaging mode and tune the Protocol to your needs, before saving for re-use, per Windows user, along with channel settings and imaging modes. Fusion provides automated tools to combine neighbouring images into large area datasets in 2D and 3D.
This is often known as tiling, or montage. Central to the Dragonfly concept is the goal of maximizing throughput, which is achieved by optimizing both imaging performance and data flow. Fusion and Imaris provide seamless transitions from imaging to deconvolution, visualization to analysis. As a result you spend more time collecting high quality data and less time pre-processing and transferring between systems. Hypothesis testing is a fundamental part of the scientific method. The familiar cycle of data creation and evaluation are delivered by the Dragonfly workflow, supporting demanding experimental regimes.
Extended observations, large fields of view and high quality data provide the input for powerful statistical analysis and data mining. All the necessary functionality for data management, visualization, analysis, segmentation and interpretation of 3D and 4D microscopy datasets with Imaris. Welcome to a new era of data interpretation, plotting and presentation. ImarisVantage enables you to compare and contrast experimental groups by visualizing your image data in five dimensions as uni- or multi-variate scatterplots.
ImarisVantage allows researchers to dissect their multi-dimensional, multi-object images by creating a series of fully customizable plots for better understanding of hidden relationships and associations between calculated measurements, objects or groups of objects. FilamentTracer is the most advanced software product for the automatic detection of neurons dendritic trees, axons and spines , microtubules, and other filament-like structures in 2D, 3D and 4D.
When combined with ImarisTrack, detection of temporal changes in length and volume of developing spines and dendrites will help researchers understand alterations caused by developmental and environmental changes. ImarisLineage is the new module which builds on the functionality of the powerful and widely used ImarisTrack. ImarisLineage enables creation of an interactive lineage tree where the cell fate can be traced from one progenitor cell to the final generation.

This image of synaptome mapping in the hippocampus is comprised of fields captured using a x objective, four wavelengths for each tile. With no image processing, no single tile is detectable by eye. Data set took just 50 minutes to capture. Courtesy of Drs.
Bacteria on Biofilm. Biofilm naturally has a high background, making imaging the bacteria on it challenging. This is evident from the widefield image. Using the confocal dramatically improves visualisation of the bacteria by eliminating the background from the biofilm. Additional deconvolution improves the image yet again.

Using GPU processing, ClearView deconvolves at speeds 30x faster than the market leading non-GPU based solution and can run simultaneously with image capture so saving you from post capture processing and delivering a more efficient workflow. Determining the stage of mitosis by the centromere number. Researcher wanted to count the number of centromeres in a large number of samples to work through to be able to test hypothesis with control and experimental groups.
The speed Dragonfly could capture these multi-dimensional images saved them critical time.
In addition the resolution, high signal and lack of photobleaching made it easy to visualise the centrioles as well. Autofluorescence in plant cells. Image captured using a 63x glycerol immersion objective. Excited at and nm. Sample type - Mouse Colonic Epithelial Organoid.
