The need for high-resolution earth observation data with frequent revisit times is ever-increasing for numerous fields including resource management, emergency monitoring and climate modeling. While satellites are commonly used to fill these requirements traditional EO satellites are large requiring long development times, high launch costs and high risk. By developing smaller satellites with smaller costs and short development times this risk can be substantially reduced. Utilizing the Cubesat standard, multiple satellites can be deployed to reduce revisit rates and achieve affordable mission reliability through redundancy. However, as the SNR of the system is proportional to the aperture of the system deployable mechanisms could be the key to high-resolution imagery on such small instruments. We discuss the design, development, manufacture, and testing of a deployable baffle for stray light attenuation for a hyperspectral imager as well as the optical performance demonstrated through the test of an engineering model of the design. The collapsed baffle and imager fit in a standard 1U payload and can attenuate light by a factor of 100 at the designed exclusion angle.
