  The aim of this paper is to provide uniform estimates for the eigenvalue
spacings of one-dimensional semiclassical Schr\"odinger operators with singular
potentials on the half-line. We introduce a new development of semiclassical
measures related to families of Schr\"odinger operators that provides a means
of establishing uniform non-concentration estimates within that class of
operators. This dramatically simplifies analysis that would typically require
detailed WKB expansions near the turning point, near the singular point and
several gluing type results to connect various regions in the domain.
