Resolution from perfect lens
WebOct 24, 2013 · In principle a “perfect lens” could be created that opens up a brave new world of scientific investigation, particularly in nanotechnology and the biosciences. The key requirement of these instruments is to devise a cunning way of getting around the diffraction limit, which restricts the resolution of images produced with optical light. WebMar 12, 2024 · For a 2.74um pixel pitch, the Nyquist frequency is 91lp/mm, 129lp/mm, 182lp/mm for R/B, G, K correspondingly. If you stop down the 160lp/mm 80lp/mm lens, you may be able to achieve the 129lp/mm across field, assuming an RGB variant of the camera. This would imply your system is sensor-limited, but require a longer exposure time.
