We present a new approach to constraining a density structure in the disk model describing the circumstellar disk around an early-type star using a combination of long-baseline interferometric observations obtained in the Hα region and the K-band. We apply this technique to observations of B-type stars with circumstellar disks obtained with the Navy Prototype Optical Interferometer and the Palomar Testbed Interferometer and discuss the complementarity of the two data sets. The benefits of this multi-wavelength approach are also demonstrated in the context of actual sources and their best-fit models.
