Abstract: A method of creating thermal boundaries in a substrate is provided. The method includes forming the substrate with first and second sections to be in direct thermal communication with first and second thermal elements, respectively, machining, in the substrate, first and second cavities for defining a third section of the substrate between the first and second sections and disposing a material having a characteristic thermal conductivity that is substantially less than that of the ceramic in the first and second cavities.

Abstract: An optical sensor and filter assembly is provided and includes an optical sensor, a filter and a mounting structure. The optical sensor includes a detector layer having first and second opposed faces and a read-out integrated circuit (ROIC) to which the first face of the detector layer is hybridized. The filter permits passage of one or more wavelength bands of interest of incident light toward the optical sensor and the mounting structure directly hybridizes the filter to the second face of the detector layer.

Abstract: An apparatus includes an optical detector configured to detect at least a portion of incoming radiation. The apparatus also includes an optical component configured to provide at least the portion of the incoming radiation to the optical detector. The apparatus further includes at least one flexure that mounts the optical component to the optical detector. Each flexure is configured to deform in response to expansion or contraction of at least one of the optical component and the optical detector. Each flexure may include a side surface that is flexible in a first dimension and rigid in second and third dimensions, where the dimensions are orthogonal to each other. The optical component may include at least one of a filter, a lens, a polarizer, an aperture, and a cover.

Abstract: A method of creating thermal boundaries in a substrate is provided. The method includes forming the substrate with first and second sections to be in direct thermal communication with first and second thermal elements, respectively, machining, in the substrate, first and second cavities for defining a third section of the substrate between the first and second sections and disposing a material having a characteristic thermal conductivity that is substantially less than that of the ceramic in the first and second cavities.

Abstract: A device includes a substantially planar platform. The device also includes a detector connected to the platform. The device further includes multiple cold fingers including a first cold finger and a second cold finger. Each cold finger has an end portion connected to the platform. Each cold finger is configured to be fluidly coupled to a corresponding cryocooler. Each cold finger is configured to absorb thermal energy generated by the detector. The second cold finger has a flexure region at the end portion.
