Objective lensfunction

Eyepiece Lens: The lens you look through in a microscope which further magnifies the image produced by the objective lens.

The objective lens is the primary lens in a microscope that gathers light from the specimen and focuses it to create an image. It is critical for determining the magnification and resolution of the microscope.

Compound Microscope: A microscope that uses multiple lenses (objective and eyepiece) to achieve higher levels of magnification.

Numerical Aperture (NA): A dimensionless number that characterizes the range of angles over which the system can accept or emit light.
