Abstract

We have developed a suite of novel infrared-blocking filters made by embedding diamond scattering particles in a polyimide aerogel substrate. Our developments allow us to tune the spectral performance of the filters based on both the composition of the base aerogel material and the properties of the scattering particles. Our filters are targeted for use in a variety of applications, from ground-based cryogenic telescope experiments to space-based planetary science probes. We summarize the design, fabrication, and characterization of these filters. We investigate several polyimide base aerogel formulations and the effects of loading them with diamond scattering particles of varying sizes and relative densities.
