The Optical Fractionator probe is often the most appropriate stereological tool for counting the number of cells (or other objects) within a 3D region of interest. It yields accurate, quantitative data using reliable, proven methodology. This seemingly basic knowledge about a specimen can be immensely important, for example, helping researchers determine whether an experimental treatment affects the total number of cells within a brain region when compared to an untreated group.
Stereo Investigator provides the Optical Fractionator workflow which offers an easy-to-use, easy-to-learn interface that walks users through the complex process of correctly using the Optical Fractionator probe. New lab members can learn the process and be up and running quickly, while avoiding counting mistakes. This probe relies on systematic random sampling to obtain a statistically valid and unbiased sample of the region of interest. Stereo Investigator overlays a 3D disector (as appropriate for the specimen) that indicates where in the specimen to count cells using the probe. Once counting is complete, results are automatically calculated and can be viewed within the software, exported to Excel, or copied to the clipboard.
In addition to the widely used Optical Fractionator probe, Stereo Investigator includes over 20 other stereological probes and estimators to evaluate numbers of objects, length, surface area, or volume/area of regions of interest. If you are looking for morphometric data in your research, Stereo Investigator can help you collect it in a way that is unbiased and repeatable.
Some examples include estimating:
For fluorescence microscopy, where minimizing light exposure is typically a concern, you can conduct stereological analyses on acquired images, rather than on a live microscope-camera feed. If desired, Stereo Investigator can help you save time on the microscope and space on image-storage devices by acquiring images from a representative portion of your specimen using systematic random sampling (SRS). Once you’ve acquired a set of statistically representative image-stacks, you can run many stereology probes for different types of morphometric analyses and never have to worry that your fluorescence signal will fade. In addition, you can repeat analyses easily if desired.
For SRS image/image-stack acquisition, Stereo Investigator directs the motorized stage, camera, and light sources. You can configure image-acquisition parameters, then let Stereo Investigator automatically capture image stacks at each SRS site. Perform stereological analysis on the acquired images using Stereo Investigator installed either on the microscope-control computer or on a different computer with the Desktop version of Stereo Investigator software.

Most Stereo Investigator systems are microscope based. It’s often fastest and easiest to evaluate specimens directly on the microscope. We also offer the Stereo Investigator Desktop Edition that does not include microscope-control elements. With the desktop edition, you simply open previously acquired 2D images or 3D image stacks and perform the probe away from the microscope, freeing up the microscope for other uses.
Stereo Investigator can integrate with all 4 major microscope manufacturers (Zeiss, Olympus, Leica, and Nikon), but depending on your microscope model, components, and experimental needs, your current microscope configuration might require upgrades or selective substitution of components. Some of the most critical components are stage, focus drive, cameras, and light sources. Please contact us to assess the compatibility of your existing microscope hardware and help you configure the optimal Stereo Investigator system for your research.
The following MBF software modules require Stereo Investigator to function and can help improve your microscopic imaging process:
Stereo Investigator: Microscope Edition is the most versatile and comprehensive version. It enables you to perform stereology directly on a microscope by controlling your microscope components, such as the motorized stage and camera. In addition to running nearly all stereological probes, you can document your experiments by acquiring images with sample and region localization so that it is easier to navigate and record your experiment.
Stereo Investigator: Desktop Edition has all the same probes as Microscope Edition, but is intended for use away from the microscope. With this version, you can work from 2D images or 3D image stacks acquired previously. This frees up busy microscopes for other users and uses.
Yes! In addition to stereological analysis, Stereo Investigator offers the 3D Serial Section Reconstruction module. This enables you to map and reconstruct your regions of interest, view your data in 3D, and create and export movies or models for presentations.
"Our Stereo Investigator system works perfectly. We use it every day and don't have any problems whatsoever. Thanks for the good system."
"I have been using the Neurolucida and Stereo Investigator software from MicroBrightField for the last 5 years, and this software has become an essential part of my research program. Whether it is 3 dimensional reconstruction, counting particular particles or mapping the developing and adult vascular, these programs are a scientific must. I personally have been able to push my research in ways that would otherwise not have been possible. Furthermore, the ability to quantitate and detect subtle differences is and will continue to be critical to my scientific program. I would highly recommend these companion programs to any research scientist."
