  We try to retrieve the power spectra with certainty to the highest spatial
frequencies allowed by current instrumentation. For this, we use 2D inversion
code that were able to recover information up to the instrumental diffraction
limit. The retrieved power spectra have shallow slopes extending further down
to much smaller scales than found before. They seem not to show any power law.
The observed slopes at subgranular scales agree with those obtained from recent
local dynamo simulations. Small differences are found for vertical component of
kinetic energy that suggest that observations suffer from an instrumental
effect that is not taken into account.
