We have presented the first identification of edge-on circumstellar disks outside of the Orion and Taurus star forming regions. Compared to the majority of edge-on circumstellar disk sources in Taurus, the two edge-on disks in the Ophiuchus region appear to be at an earlier evolutionary stage, as they are still more deeply embedded in their circumstellar envelopes. The high-spatial resolution infrared data confirm that the difference in the spectral energy distribution of CRBR 2422.8-3423 and HH 30 is due to a slight difference in the inclination of the disks to the line of sight, as had been predicted previously by theoretical models.
