Abstract: Described herein are deadfront assemblies that are configured to exhibit variable transmission and reflection performance attributes. The deadfront assemblies described herein comprise a first ink layer, an intermediate layer, and a second ink layer. The intermediate layer is disposed between the first and second ink layers and is configured to reflect light that is transmitted through the first ink layer back through the first ink layer so that one or more colors of the ink in the first ink layer is visible in the reflected light. The second ink layer is configured to counteract deviations in optical transmission caused by the first ink layer so that light transmitted through the deadfront assembly is not perceptively altered in color. Overlapping regions of the first and second ink layers comprise inverse appearance attributes so that light output from a light source and transmitted through the deadfront assembly has a desired appearance.

Abstract: For testing or production of a semiconductor-based detector in SPECT, an interposer, such as elastomeric device with conductors, is sandwiched between a carrier and the semiconductor detector.
