Count cells and quantify lengths, areas, and volumes with the world's best and most-cited stereology system
A Stereo Investigator® system for stereology gives you accurate, unbiased estimates of the number, length, area, and volume of cells or biological structures in a tissue specimen. It is a key research tool that has helped lead advances in numerous areas of neuroscience including neurodegenerative diseases, neuropathy, memory, and behavior, as well as other research fields including pulmonary research, spinal cord research, and toxicology.
Stereology with Stereo Investigator can be done on a microscope system or from image stacks acquired in a manner suitable for stereology.
Fully Integrated Microscope Systems
In addition to stereology software, a Stereo Investigator system includes any hardware you need, such as a microscope, computer, motorized stage, camera, etc., and comes with MBF’s technical support for the entire system as well as research support to optimize your experimental design.
Stereology on a Microscope
Microscope hardware and Stereo Investigator software work in harmony to deliver a powerful, seamless stereology system. A typical system includes a microscope, computer, and Stereo Investigator software. Most of what is visible through the oculars is displayed on the computer screen.
Stereo Investigator fully integrates with your microscope and associated hardware to reduce manual work and to speed up data collection. It can:
- direct motorized stages to automatically move for systematic random sampling of tissue specimen
- control cameras so you can view live images or collect and save images and image stacks, even change or save camera settings for future use
- control the focus position, change objective lenses or adjust the condenser
- automatically change filter wheels and mirror cubes when acquiring fluorescent images or image stacks
Stereo Investigator works with brightfield, multi-channel fluorescence, confocal, structured illumination, and two-photon microscopes.

Stereology from image stacks
Performing stereology at the microscope from fluorescent tissue specimens can be problematic since exposure to light degrades fluorescent tissue. With Stereo Investigator you can acquire image stacks using systematic random sampling (SRS) - a method that produces image stacks suitable for stereology- and then perform stereology on the image stacks. A great benefit of stereology on image stacks is that you can run many probes for different types of analyses and never have to worry that your tissue will fade. Plus, it's easier to double check the analysis.
During SRS image stack acquisition, Stereo Investigator directs the motorized stage, camera, and, for fluorescent images, the filter wheels and mirror cubes. This means you can automatically capture image stacks at each sample site, and then take the image stacks to a computer with Stereo Investigator Desktop and perform stereological analysis.
Stereology on whole slide images
Stereo Investigator can quickly and easily create whole slide images of your entire specimen in 2D (x, y) or 3D (x, y, and z) with the addition of the 2D and 3D Slide Scanning modules. The system is fully integrated and works unattended, allowing you to focus on other projects. Stereo Investigator directs the motorized stage, camera, and, for fluorescent images, the filter wheels and mirror cubes so there is no need for manual intervention.
Whole slide images give you the freedom to perform stereology on a computer away from the microscope. Stereology on 2D whole slide images can be employed if the chosen probe does not require systematic random sampling, such as Cavalieri probe for regional area and volume, and Area Fraction Fractionator for calculating the area of a small subregion (such as lesions or plaques) within a larger region.
