I learned in October 2022’s Breakthrough that the spikes of stars in high-power photos are called diffraction spikes. Why do they appear as two crosses at 45 degrees to each other? The diffraction ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
