Deep optical and near-infrared imaging observations of five low- to intermediate-luminosity pre-main-sequence stars embedded within dense cores reveal an extended emission component. Four of the five stars were previously identified as outflow sources. Nebulosity is detected with the optical and J and H bandpasses for each source. The large measured polarization values (p = 10 to 70 percent) at H and K identify the nebulosity as scattered light. At K the intensity distribution is generally less extended than at J and H, and is characterized by an additional, unresolved component. The position of this point source likely identifies the location of the newborn star within the field. For all sources, the illuminating star is redder than its associated nebula. The observed correlation of cometary reflection nebulae with newborn stars undergoing mass outflow suggests that the low-opacity paths are cavities associated with energetic stellar winds.
