It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

A team of scientists in the lab of Changhuei Yang at Caltech has developed an inexpensive, robust method for autofocusing microscopes that involves little more than a couple of LED lights and some ...

Researchers have developed a way to retrofit the transmission electron microscope -- a long-standing scientific workhorse for making crisp microscopic images -- so that it can also create high-quality ...

Which digital microscopes are best? Whether an academic researcher or a casual hobbyist, the microscope is an essential part of nearly every scientist’s toolkit. While all microscopes let you examine ...
