A compound microscope typically has 3 to 5 objective lenses. These lenses are the primary magnifying components of the microscope.
Microscopes are essential tools in various fields, particularly biology and medicine, allowing for detailed examination of small structures. The objective lenses, positioned closest to the sample being observed, play a crucial role in the overall magnification and image quality.
Common Objective Lens Magnifications
The most common magnification powers found on objective lenses include:
- 4x: Provides the lowest level of magnification, often used for initial scanning of a slide.
- 10x: Offers a moderate magnification for general viewing and identifying specific areas of interest.
- 40x: Provides higher magnification for detailed observation of cellular structures.
- 100x: Requires the use of immersion oil and offers the highest magnification, allowing for the visualization of fine details within cells.
The total magnification of a compound microscope is calculated by multiplying the magnification of the objective lens by the magnification of the eyepiece lens (typically 10x). Therefore, using a 40x objective lens with a 10x eyepiece provides a total magnification of 400x.
