A dissecting microscope uses a system of lenses to magnify specimens for detailed observation.
Understanding the Magnification Process
The core function of a dissecting microscope involves two primary lens systems:
- Objective Lens: This is the first lens, positioned close to the specimen. It collects the light reflecting off the specimen and begins the magnification process.
- Ocular Lens: Also known as the eyepiece, this lens further magnifies the image projected by the objective lens, allowing the observer to see a larger, more detailed view.
| Lens Type | Function | Location |
|---|---|---|
| Objective | Collects light and initiates magnification. | Closest to the specimen |
| Ocular | Further magnifies the image from the objective lens. | Eye level |
Practical Application
Dissecting microscopes are often used for:
- Viewing larger specimens, such as insects, plant parts, or small geological samples.
- Performing dissections or manipulations on samples while viewing.
- Observing three-dimensional objects due to their larger working distance (space between objective lens and specimen).
These microscopes provide a magnified view that is upright and not inverted, which is essential for manipulation and observation purposes. The system of lenses work together to create a magnified view.
