An optoelectronic module that includes a reflectance member which exhibits mitigated or eliminated fan-out field-of-view overlap can be concealed or its visual impact minimized compared to a host device in which the optoelectronic module is mounted. In some instances, the reflectance member can be implemented as a plurality of through holes and in other instances the reflectance member may be a contiguous spin-coated polymeric coating. In general, the reflectance member can be diffusively reflective to the same particular wavelengths or ranges of wavelengths as the host device in which it is mounted.

An occulting assembly for use with a telescope or other imaging instrument when viewing the sun or other bright light source. An occulting disk is supported by a set of thin stiff truss rods. These truss rods are attached to the dark side of the adapter at one end and to an adapter at the other end. The adapter provides a mechanical interface to the telescope or other imaging instrument and has an aperture piece that defines an aperture in its center. The occulting disk is sized to completely shadow the aperture and the truss is arranged so that it is within the shadow of the occulting disk.
