Objective lens microscopefunction

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.

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

Numerical Aperture: A dimensionless number that characterizes the range of angles over which the system can accept or emit light, influencing the resolving power of an objective lens.
