An apparatus includes a top surface configured to couple to a variable aperture mechanism (VAM), where the top surface has an opening configured to align with an aperture of the VAM. The apparatus also includes a bottom portion configured to couple to a cooled object and a contact portion configured to couple to a strut, where the top surface, bottom portion, and contact portion form a continuous body. The apparatus further includes a plurality of baffles within the continuous body, where each of the baffles has an opening configured to align with the aperture of the VAM. In addition, the apparatus includes a reinforcement ring comprised in or within the continuous body and disposed to be aligned with the strut when the strut is coupled to the continuous body.

Structurally reinforced composite cold shield for use in infrared sensors or other devices

An Infrared Detector Dewar system includes a housing and an infrared detector. The system also includes one or more strut members coupled on a first end to the housing. The system further includes cold shield coupled to the infrared detector and to a second end of the one or more strut members. The cold shield includes a reinforcement ring aligned with the one or more strut members. The cold shield is formed by forming a support member having disc encased by a support ring. The support member is positioned within a mandrel such that the reinforcement ring is disposed to align with a strut position. The cold shield is then formed by electroplating copper over the mandrel and at least a portion of the support member, and then by removing/dissolving all aforementioned mandrels.
