The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

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 ...
