Point Resolution (or Point-to-Point, or Directly Interpretable Resolution) of
a microscope corresponds to the to the point when the CTF first crosses the
k-axis at the extended
scherzer defocus and can be expressed as:
|
|
Phase contrast images are directly interpretable only up to the
point resolution (Scherzer resolution limit).
|
If the information
limit is beyond the point resolution limit, one needs to use
image simulation software to interpret any detail beyond point
resolution limit.
