WebMay 4, 2016 · However, achieving diffraction-limited focusing of the THz beam is a non-trivial task since it requires THz emission with frequency-independent divergence and … WebA diffraction limited lens is a lens where aberrations are so small that performance is limited by diffraction. This is very hard to achieve in a camera lens. But you only work at one wavelength. You have a very simple optical situation where you want to focus a collimated beam to a point on axis. And most of all, your wavelength is 10.6 um. WebA laser beam is called diffraction-limited if its potential to be focused to small spots is as high as possible for the given wavelength, limited only by the unavoidable diffraction . In other words, its beam quality is ideal. … bai mei supermarket
