On the conducting surfaces, the resolution limit is estimated as 2 nm.
The photo was grainy, blown up to near the resolution limit.
It appears that the resolution limit will be an insertion each three amino acids on average in a target protein.
Thus, the resolution limit is usually around λ/2 for conventional optical microscopy.
The resolution limit in 2005 was around 0.05 nanometer and has not increased appreciably since that time.
In any case, at thirty million kilometers distance, Pearl was at the resolution limit of their best telescopes.
Instead, the seeing, or blur caused by the atmosphere, sets the resolution limit.
However, it has recently demonstrated that Q suffers a resolution limit, what produces unreliable results when dealing with small communities.
Optical lithography pushed beyond its natural resolution limit has a significant advantage in this regard.
This defines the resolution limit and the basis of visual acuity.
