Most compound microscopes come with interchangeable lenses known as objective lenses. Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power, and (typically) oil immersion objectives, respectively.
What is the function of the nose piece?
Nosepiece: A rotating turret that houses the objective lenses. The viewer spins the nosepiece to select different objective lenses. Objective lenses: One of the most important parts of a compound microscope, as they are the lenses closest to the specimen.
