Many different types of optical imaging and sensing systems are used to observe and measure the Earth and the universe at large. However, designing optical systems for satellites and spacecraft is challenging due to the harsh conditions that space places upon components and systems working in this remote environment. Lenses that are used in space applications have to meet certain basic requirements to survive the harsh environment of space. For instance, the orbit that optical systems operate in determines how much radiation they will be required to withstand. In addition, lenses must be constructed of specific materials that will not outgas when exposed to the vacuum of space.
