A convergent perturbation expansion procedure for determining the reflection coefficient for unstable convective modes in a plasma with small changes in the density is derived. If the total variation of the local wave vector is small, the lowest-order reflection coefficient can be used to determine the critical length of the system. The technique is used to determine the critical length of mirror machines which are subject to the convective loss-cone instability. Even for small rapid or large gentle changes in the local wave vector, critical lengths less than ten e-folding distances can be realized.
