Abstract: 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.

Abstract: 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.
