Vacuum energy length scale detectable by the Casimir effect?

[jcap]

According to Sean Carroll's The Cosmological constant(https://arxiv.org/pdf/astro-ph/0004075.pdf) (Eqn.20) cosmological observations imply that the magnitude of the vacuum energy density in natural units is given by
$$|\rho^{(obs)}_\Lambda|\le (10^{-12}\ \rm{GeV})^4.$$
Does this imply that the minimum length scale of the zero-point normal modes of quantum fields in the vacuum are of the order of $\lambda \sim (\rm{meV})^{-1}\sim \rm{mm}$ ?

If this is true then would this millimeter cutoff length be detectable by Casimir effect-type experiments?

I think it implies that dark energy (aka cosmological constant) is not Casimir energy. See also http://de.arxiv.org/abs/1702.03291 and references therein.

No. Because the Casimir effect can be explained without any recourse to the vacuum, it cannot tell us anything ebout the vacuum.
