Abstract

Optically black baffle surfaces are essential in determining the signal-to-noise level for many optical systems. Requirements for new, advanced optical systems indicate that new, advanced materials or improvements in current industrially available materials are needed. Broadband optically black beryllium baffle surfaces have been developed and performance of black beryllium knife-edged baffle vanes demonstrated. In this paper an overview of the requirements for baffles, optical characteristics of the developed optically black beryllium baffle surfaces, and the performance of black beryllium knife-edged baffle assembly will be discussed.
