Hard momentum cutoff is used for estimating IR/UV corrections to the Casimir force. In contrast to the power-law corrections arising from the IR cutoff, one will find the UV cutoff-dependent corrections to be exponentially suppressed. As a consequence of this fact, there is no chance to detect the corrections due to UV cutoff arising for instance from the minimum-length scenarios even if fundamental quantum-gravity scale is taken around $sim$ TeV (as is the case, for example, in various models with extra dimensions).
