Current status of SurfCam development

The Korea Astronomy and Space Science Institute (KASI) is currently developing GrainCams as a candidate payload for NASA's Commercial Lunar Payload Services (CLPS). GrainCams consists of two instruments to be mounted on a rover: LevCam, which observes levitating dust near the lunar surface, and SurfCam, designed to observe lunar regolith. Over the past two years, LevCam and SurfCam have been engaged in optical and optomechanical design work, conducting various analyses to assess manufacturability. SurfCam, being a light field camera, has seen the development of a prototype to measure initial optical performance, along with conducting preliminary assembly and alignment. Despite some minor optical specification changes this year, the overall development is still ongoing. The paper will cover SurfCam's assembly and alignment strategies and performance measurement aspects.
