There are several limitations of using a 100X oil immersion objective lens over another lens during microscopy:
1. Limited field of view: The high magnification of the 100X lens results in a smaller field of view compared to lower magnification lenses. This means that only a small area of the sample can be observed at a time, making it difficult to study larger structures or get an overall view of the sample.
2. Reduced depth of field: The depth of field, which refers to the thickness of the sample that appears in focus at a given time, is significantly reduced with the 100X lens. This can make it challenging to observe structures that are not on the same focal plane.
3. Increased sensitivity to vibrations: The high magnification of the 100X lens makes it more sensitive to vibrations, such as those caused by the microscope stage or external factors. This can result in blurry images or difficulty in focusing on the sample.
4. Requirement of oil immersion: To achieve the highest resolution with a 100X lens, it is necessary to use immersion oil between the lens and the sample. This oil has a specific refractive index that matches the glass of the lens and the sample, improving the light-gathering ability and reducing aberrations. However, the use of oil immersion can be messy, time-consuming, and requires careful cleaning to avoid contamination.
5. Higher risk of damage: The 100X lens is more delicate and prone to damage compared to lower magnification lenses. It requires careful handling and cleaning to avoid scratching or damaging the lens surface.
6. Higher cost: 100X oil immersion objective lenses are typically more expensive compared to lower magnification lenses. This can be a limitation for laboratories or individuals with budget constraints.
Overall, while the 100X oil immersion objective lens provides high magnification and resolution, it also comes with limitations such as a smaller field of view, reduced depth of field, increased sensitivity to vibrations, requirement of oil immersion, higher risk of damage, and higher cost.
