Several advanced, lightweight, robust, broadband-diffuse absorptive baffle materials are available for sensor-system designers. These materials technologies are shown to be scaleable, and to possess target-survivable performance; they include sputter-deposited Be on cold-rolled Be ingot sheet material or Be foam, plasma-sprayed Be, plasma-sprayed B-on-Be, and CVD B4C on graphite. An account is also given of the Optics Manufacturing Operations Development and Integration Laboratory Advanced Optical Baffle Program.
