Techniques for multi-channel night vision system alignment

One example illustrated herein includes an optical device including a bridge assembly configured to connect two or more monocular tube assemblies and at least two monocular tube assemblies. Each monocular tube assembly includes a housing, an alignment member attached to the housing, the alignment member providing an indication of an optical axis of the monocular tube assembly, and an interface component that links the housing to the bridge assembly, the interface component comprising an adjustment mechanism that enables adjustment of the monocular tube assembly relative to the bridge assembly, such that the adjustment mechanism can be used in conjunction with the alignment member to align different optical axes. Aspects of the present disclosure may be implemented to allow for field-alignment of the optical device.
