Abstract
The nature of Dark Energy can by constrained by the precise determination of super-novae distance moduli in ultraviolet to near IR pass-bands. Space-based observations are required for these moduli to be measured with the scientifically required photometric accuracies. Consequently, robust pass-band filters operable at cryogenic temperatures (120-140K) are needed that have challenging performance attributes including high in-band transmission, low ripple, good out-ofband rejection, and moderate band-edge slope. We describe the requirements and performance of dielectric multi-layer filters with spectral profiles that are suitable for both achieving the science and for accurate calibration using plausible on-orbit measurement systems.
