Stereo microscopes are available in various configurations to meet different needs and budgets. Here are the main types:  

l Fixed Magnification Stereo Microscopes: These microscopes offer a single, pre-set magnification level. They are often the most affordable option and are suitable for basic observation tasks where a specific magnification is sufficient.

l Zoom Stereo Microscopes: These microscopes feature a zoom mechanism that allows for continuous adjustment of magnification within a specific range. This provides flexibility to view specimens at different magnifications without having to change objective lenses. Zoom microscopes are popular for their versatility and ease of use.  

l Turret Magnification Stereo Microscopes: These microscopes have a rotating turret that houses multiple objective lenses with different magnifications. By rotating the turret, you can quickly switch between different magnification levels. Turret microscopes offer convenient magnification changes and are often found in educational or laboratory settings.  

l Digital Stereo Microscopes: Some stereo microscopes incorporate digital cameras or video outputs, enabling you to capture images or videos of your specimens. These digital capabilities are useful for documentation, analysis, and sharing observations.  

l Specialized Stereo Microscopes: Depending on the application, you might find specialized stereo microscopes with features like:

1. Long working distance objectives: For applications requiring extra space between the lens and specimen.  

2. Ergonomic designs: For comfortable use during prolonged observation.

3. Integrated illumination systems: Including LED, halogen, or fiber optic options.

4. Specific stands and bases: For stability and compatibility with accessories.  

The type of stereo microscope that best suits your needs will depend on your specific applications, budget, and desired features.
