Numerical aperture formula with refractive index

the opposition or dissimilarity of things that are compared.

Ever since the invention of the first compound microscope by Zacharias Jansen in 1590, our understanding of the microscopic world has grown exponentially. Microscopes have evolved from mere assemblies of magnifying lenses to extremely powerful tools for visualization on the atomic scale. You can find a wealth of information on the workings of a microscope…

If you want to visualize elastic fibers in your sample, you need to use Verhoeff-van Gieson stain. Find out more about this stain, including how to use it.

Do you know what that NA number is on your objective? We walk you through what the numerical aperture is and why it's important.

Phase contrast microscopy is a light microscopy technique which is primarily used to visualise live cells. Using various filters and condensers, the image produced by phase contrast allows us to see greater detail in live cells and can highlight aspects such as intracellular structures. Keep your cells alive! The best way to view cells is…
