* Magnification: Stereomicroscopes provide a lower magnification (usually between 5x and 50x) than compound microscopes. This is ideal for viewing the whole insect, its external features, and its surface details.
* 3D View: Stereomicroscopes use two separate objective lenses and eyepieces, creating a three-dimensional image. This allows for a more realistic view of the insect's structure.
* Depth of Field: Stereomicroscopes have a larger depth of field than compound microscopes, meaning more of the insect is in focus at once. This is helpful for examining textured surfaces or intricate parts.
* Illumination: Many stereomicroscopes have built-in lighting, allowing you to illuminate the insect from different angles for optimal viewing.
While other instruments like compound microscopes or even magnifying glasses could be used, the stereomicroscope offers the best combination of magnification, 3D view, and depth of field for studying large insects.
