Definitions:

Objective Lens

is the lens closest to the object being observed in a microscope, which magnifies the image of the specimen.

Oil Immersion

A microscopy technique that involves placing a drop of oil on a slide to increase the resolution of the microscope by reducing light refraction.

Low-Power

Typically refers to a setting or mode of operation in devices that consume minimal electrical energy or to optical devices (like microscopes) using objective lenses with lower magnification.

Compound Light Microscope

An optical instrument that uses visible light and a system of lenses to magnify images of small samples.
