Definitions:

Increasing Magnification

The process of enlarging the appearance of an object through an optical device, such as a microscope or telescope.

Oil-immersion Lens

A microscope lens that uses oil immersion to increase resolution by minimizing refraction.

Field Diameter

The visible area observed through the microscope lens; its size depends on the magnification power.

High-powered Objective

An objective lens used in microscopy with high magnification capabilities, allowing for the detailed observation of minute specimens.
