Revolution® DSD2


The simple design of the DSD2 means that it can be mounted to inverted and upright microscopes and fluorescence stereomicroscopes and macroscopes. With three confocal sectioning options, you can choose the optimal setting for your sample or magnification. This makes the DSD2 probably the most versatile confocal device on the market, addressing the broadest range of sample types. With no fixed laser wavelengths to limit you, you have freedom to choose the best wavelength choice for your research. Fixed or live, there is no limit to the possibilities.


With a spinning disk at its core, the DSD2 naturally captures images at higher frame rates than a point scanning confocal. A three dimensional image, at a like-for-like resolution and comparable quality, can be captured in seconds on the DSD2 compared to minutes on a point scanning confocal. This offers two key benefits. Higher throughput of samples, so increasing productivity and earlier data review; and for live samples the ability to capture dynamics in higher temporal detail for greater insight.


The Revolution DSD2 can be used with additional Andor devices from our Photostimulation range. For example, add a MicroPoint to combine confocal imaging with ablation, such as used in damage & repair research, or add a Mosaic 3 for fast targeted illumination to use optogenetic models with DSD2. This simple device can in fact be used for sophisticated applications, now or as your research develops.


Combining structured illumination and spinning disk technologies with high sensitivity high dynamic range Andor sCMOS cameras, the Revolution DSD2 produces image quality that typically exceeds confocal images captured with laser point scanning systems. This latest generation builds on a field proven device, introducing even better performance and so even higher quality imaging.


With no lasers required for the Revolution DSD2, and the simplicity of its design making it an easy device to align, there is no risk of owning a confocal device requiring regular attention to keep it operational. The benefit is worry free imaging for many years, and extremely low maintenance costs.

The Revolution DSD2 is unique in its class in having 3 confocal settings, which we call High Signal, Medium Sectioning and High Sectioning. These settings will be chosen according to the objective magnification or sample type that you use. Typically you would expect to select High Sectioning for the most confocal image with the highest detail, as clearly demonstrated below in a sample captured at a low magnification. However, at higher magnifications and in thinner samples, you may find that to maximise on signal and sensitivity, you will need to select the High Signal setting. The choice is yours for you to capture the best quality images possible

A demonstration of the 3 settings at work on the DSD2 Images of the same sample taken using the three different disk sectors. Sample is the egg-chamber from Drosophila melanogaster at stage 10. Visible is the large oocyte with its tiny meiotic nucleus. Insets are a close-upof the nurse cells with large polyploid nuclei. You can see the improved resolution as the disk pattern moves from High signal to High sectioning. Stained are: DAPI (blue) to show the DNA, WGA-657 (green) to show membranes, primarily visible are nuclear membranes. Also stained by fluorescent in situ hybridization is the oskar mRNA that is enriched at the posterior cortex. Detection: Cy3-coupled tyramide amplification.

In order to achieve the best quality results from the Revolution DSD2 and your research we strongly recommend combining Andor iQ with Bitplane Imaris.

The DSD2 will generate large data sets, especially in fields like developmental biology and Neuroscience. Imaris has the ability to view huge Gbyte data sets from the moment the data starts loading. You can then go on to use sophisticated visualisation and comprehensive analysis tools for multi-dimensional data sets, delivering greater insight to your research that you may not have thought possible
