Space qualification is one of the most demanding qualifications within the industry. But there are ways to save time and money by using what space insiders call “heritage.”

FIGURE 1. The refractive index of UV-grade fused silica as a function of wavelength (left); this dispersion can lead to temporal distortion for ultrafast laser pulses. Attempting to focus a white light source through a single lens results in different focal planes for the various component colors (right); this is analogous to how ultrashort pulses experience temporal distortion when passing through a medium.
