If you’ve ever asked yourself “What is the maximum magnification of a light microscope?” you’re not alone. Calculating the maximum magnification of any optical microscope (sometimes referred to as a light microscope) is a matter of multiplying the magnification of the light microscope’s two lenses.

Compound optical microscopes were invented in the 17th century, and they use a set of two lenses to magnify a specimen. Light microscopes use natural light (either ambient light or light from a power source) to magnify the image of small samples or specimens.

The most powerful light microscopes capture their images with light-sensitive cameras to generate a micrograph. In the old days these images were captured on photographic film, but now with a number of microscopes coming with USB ports, it’s easy for young scientists to capture digital images and download them directly to their computer.

About the Lenses and Magnification of Light Microscopes

Light microscopes have two lenses, an optical and an objective lens and the maximum magnification of a light microscope is determined by multiplying the magnification levels of each lens which is used.

Standard Magnification Levels of Objective Lens

The magnification level of an objective lens on a light microscope will typically range from 5x magnification all the way up to 100x magnification. Some extremely high-performing ocular microscopes require matching magnification levels on the eyepiece to deliver the best performance.

Standard Magnification Levels of Ocular Lens

The eyepiece of most light microscopes comes with a few standard levels of magnification which range from 5x to 10x (probably the most common), and all the way up to 15x and 20x.

The Maximum Magnification of a Light Microscope?

On a stock, high-performance compound light microscope, magnification levels of 1000x can be achieved (10x ocular lens, 100x objective lens). With that said, the maximum magnification level of a light microscope at the high end of the performance spectrum is 2000x magnification (20x ocular, 100x objective).

As with many things, the more nuanced answer is "it depends".
