An objective lens is a crucial component of a microscope that gathers light from the specimen and focuses it to create a magnified image. The quality and type of objective lens used can significantly affect the clarity, resolution, and overall detail of the observed specimen. Objective lenses come in various magnifications, typically ranging from low to high power, allowing for different levels of detail when examining cellular structures.

Fresnel lenses are known for their light weight, compact size, and versatility, which makes them a popular choice in the magnification field.

The ridges on a Fresnel lens bend and focus light, similar to the way a curved lens works. However, the ridges are angled to allow the lens to be thinner and flatter. This design makes Fresnel lenses more versatile and easier to use.

Overall, Fresnel lenses are an important tool in optics and can provide advantages in terms of cost, weight, and size compared to traditional curved lenses.

Resolution: The ability of a microscope to distinguish two close points as separate, which is essential for observing fine details.

A Fresnel lens is a type of optical lens that is composed of a series of concentric grooves or ridges on a flat surface, rather than a traditional curved lens. This design allows for a thinner and lighter lens with similar or greater focusing power compared to a curved lens of the same size.
