Q: Do I need radiation tolerant lenses for my space application?
A: The impact of cosmic radiation on your lens or optical system is a major consideration when designing for use in #space. Unfortunately, standard optical glass types turn brown or grey when exposed to radiation. As a result, the light transmission through your lens is significantly decreased, greatly effecting its performance. If the mission is short enough, then you may be able to get away with using standard glass types. However, for longer missions, specialist radiation tolerant cerium doped glass must be used.
